## Why is the metric system important?

The metric system has been adopted by most countries because it is an easy system to use. Everything is based on the number ten. This is called a decimal system. Basically, all you need to do in order to change numbers to larger or smaller units is multiply or divide them by ten.

## When did we change to metric?

… units of measurement of the British Imperial System, the traditional system of weights and measures used officially in Great Britain from 1824 until the adoption of the metric system beginning in 1965. The United States Customary System of weights and measures is derived from the British Imperial System.

## Why do scientists use the metric system?

Unlike the British Imperial System, the metric system, or SI (from the French Système International), is based on a natural constant. SI is designed to make measurements and calculations easy to perform and understand, which is one of the main reasons scientists use it.

## Why is Imperial better than metric?

The basis of the argument is that while the metric system of units is based on scientific constants, the imperial system is based on the size of everyday items. From Real Clear Science: While the metric units’ association with physical constants makes them accurate, it makes them less practical for common use.

## Does NASA use metric?

Although NASA has ostensibly used the metric system since about 1990, English units linger on in much of the U.S. aerospace industry. In practice, this has meant that many missions continue to use English units, and some missions end up using both English and metric units.

## Who is the father of measurement?

In the middle of the 19th century, James Clerk Maxwell conceived a coherent system where a small number of units of measure were defined as base units, and all other units of measure, called derived units, were defined in terms of the base units. Maxwell proposed three base units for length, mass and time.
