There are two major measurement systems in the world that are used to gauge distances, weights and volumes. These are the Imperial (British) system and the Metric system.
The vast majority of countries worldwide employ the metric system of measurement, which is comprised of units like meters, liters, and grams. Magnitudes of 10, 100, 1000 of these units are represented by the addition of appropriate prefixes such as deci, centi, and milli. Ex: centimeter, kilogram.
In the United States, the old imperial system of measurement is employed, which consists of units such as feet, inches and pounds.
The imperial system, which is also called the British imperial since it originated in the British empire that ruled several regions across the globe from the 16th to the 20th century. One of these regions gained independence and later became the United States of America in the 18th century. The government of the nascent country decided to retain the Imperial measurement system, despite the popularity of the metric system in that era.
Following are some of the corresponding values between the Metric and British systems:
- A single mile is approximately 1.6 kilometers
- 1 inch is approximately 25 millimeters or 2.54 centimeters
- One meter is the same as a three foot measurement
- A kilogram is equivalent to 2.2 pounds
- 1 pound is equal to 454 grams
- A 100 pounds is the same as 7.14 stones
There are other differences that arise when considering either of the measurement systems. For example, let us look at the way of observing temperature. Americans measure temperature in Fahrenheit, whereas people of other countries do so in centigrade.
Conversions for temperature include 0 degrees Celsius being equal to 32 degree Fahrenheit, which is essentially the freezing point. 24 degrees Celsius is tantamount to 75 degrees Fahrenheit, which means the weather is likely to be pleasant. The formula for conversion from C to F is, C multiplied by 1.8 and adding 32 to that number.
As it stands, there is no reason to expect the United States to follow suit and change to the metric system. As there are no imminent plans for the change, visitors traveling to USA should familiarize themselves with the British measurement system.

Amita Vadlamudi an Information Technology professional volunteers at a local public library working as a shelf reader. Amita Vadlamudi finds it interesting to learn how information has been recorded and disseminated throughout human history.
Libraries have existed for thousands of years. In the 1850’s British archaeologists discovered two of the oldest libraries in Northern Iraq, the region that was part of ancient Mesopotamia. It is believed that the libraries belonged to King Sennacherib of Assyria who ruled from 704 to 681 b.c. His grandson Ashurbanipal was credited with assembling the huge collection of records from kingdoms and empires prior to his time.
The collections contained in these libraries were in the form of clay tablets. The ancient people of Mesopotamia recorded information on wet clay that was later baked and dried. The writings on these dried clay tablets remained durable for thousands of years, although modern scholars are unable to translate the meaning of them.
Libraries of clay were also found during excavations in the ancient cities of Syria and Turkey.
Dogs by far make the best pets. They are affectionate and loyal to their owners and bring great companionship and happiness.
There are hundreds of breeds of dogs. Retrievers, poodles, terriers, collies, German shepherds, Dalmatians, and beagles are some of the most popular breeds. Dogs come in many sizes. Smallest is the Chihuahua which weighs around 1.8 kilograms (4 pounds). St. Bernard breed is the heaviest at around 90 kilograms (200 pounds). Dogs vary greatly in appearance. Some barely look like dogs. Some dogs have so much hair that they look like small wooly mammoths. Some have no hair at all. Some have so much skin that they look like they are wearing a thick quilt. Some dogs look mean when in fact they are docile. Other dogs look attractive, when in fact they might be troublesome.
Physical appearance is only one of the characteristics that go into the selection of a dog as a pet. Their temperament and their behavior is what is even more important. One thing for certain is that people love their dogs regardless of the dog’s look.
Dogs are loving, loyal, and comforting. However, they are not always obedient or easy to take care of. They demand much time. They need to be walked in all types of weather. Their food, grooming, kenneling, and medical bills could be costly. Prospective pet owners much do a thorough research on the suitability of the dog before they decide to take on the responsibility. They must clearly weigh the pros and cons of owning a pet and prepare to make a serious commitment. There are many good books available on dogs and pets in the book stores, libraries, and online.Dogs certainly make great reading, and if properly chosen, dogs make great pets.

Coin collecting is a hobby enjoyed by many around the world. Indeed it is one of the oldest hobbies even from the ancient times, engaged by royalty and academia. A lot can be learned from coin collecting such as history, culture and politics and can be shared with and passed down the generations.
The technical name for coin collecting is numismatics. It is the collection and study of coins as well as the paper money from around the world for their artistic value rather than their monetary face value.
History of Coin Collecting
There has been a lot of evidence that coin collecting was a prominent hobby in the Roman era. Suetonius’ De vita Ceasarum shares that emperor Augustus was fond of old and foreign coins and would give them as gifts to his friends. It is thought that coins have been collected since as long as they have existed.
Some scholars have contested that it is the Italian Renaissance that gave birth to coin collection, but numerous Greek and Roman accounts argue otherwise.
The hobby of coin collecting surged back into popularity during the Renaissance period. During the 15 and 16th-century, ancient coin collecting became the hobby of the kings. In the 17th century the nature of collecting geared more towards serious research.
It became an academic pursuit and a lot of guidelines were published.
Types of Coin Collectors
Novice: This is someone who collects coins as they come across them. They don’t have a specific theme and rely on friends or family to give them the coins.
Hobbyist: This person collects coins as a hobby. They are in the beginning stages and want to own a small specific collection without having to spend a lot of money. They may be a part of the coin club or be affiliated with a local coin shop where they engage in trading.
Generalist: this person has coins from all around the world. They don’t focus on any particular sort of coin. One of Egyptian kings from early 1900’s, King Farouk was known to be a generalist who collected coins of huge variety and scope.
Specialist: This person is the opposite of the generalist and focuses specifically on one sort of coin collection such as a particular historic period.
Completists: This person collects every type of coin within a certain category. A collector named Louis Eliasberg is known to have collected a complete set of all the known coins the United States.
Coin Collecting as an Investment
There is a good market for coins for people who want to engage in trading coins. The price of the coins is often fluctuating and the right move at the right time can yield good profits. Rare coins can bring in top dollars.

Hiking is an outdoor activity which involves walking in natural environments, often on hiking trails. With hiking, you can view great landscapes, get exercise and fresh air, become refreshed, and improve your health. Before you set out on your first hiking expedition, however, it is important to do some research and take steps to insure a safe hiking trip.
Be smart: when you are planning on going on a strenuous hike please make sure to start working out a week or two prior to that. You must build up your stamina gradually and not push yourself more than you can handle.
Let others know: before you are about to leave let your family or friends know where you are going, whether you are going alone or with a group of friends. Tell them that you will contact them when you get back (and do contact them to avoid them sending a search party after you). It is always preferable to go in groups rather than going alone, especially as a beginner.
Know where you are going: as a beginner, it is better not to improvise your hike, better that you know where you are going unless you are with an experienced hiker. Bring a compass along, also pay attention to the landmarks as you pass them by.
Bring a lot of water: All that walking would require you to keep yourself hydrated. If you are going on very long hikes it helps to carry water purifying tablets with you.
Dress for the part: Keep one or two pieces of warm clothing and a raincoat because the weather can be unpredictable sometimes. In cold weather, dress in layers. Buy good quality hiking shoes and socks to prevent blisters.
Keep a first aid kit and some precautionary items: You need a first aid kit to treat injuries and prevent infections. Bring along sunscreen, bug spray, pepper spray, pocket knife, and sunglasses. Although you might not get a good reception on some hiking trails and wilderness, it is still a good idea to bring along a fully charged cell phone and also a portable charger.
Taking a few good precautions will get you a long way in insuring a safe and enjoyable hiking trip.
