It uses units such as meter, liter, and gram to measure length, liquid volume, and mass. It was made compulsory by France in Today, it is the system of measurement throughout the global scientific community.

So why do some countries still use imperial measurements? Overall building dimensions for new construction are usually in SI units.. Britain is officially metric, in line with the rest of Europe.

However, imperial measures are still in use, especially for road distances, which are measured in miles. Imperial pints and gallons are 20 per cent larger than US measures. The computer display readouts were in units of feet, feet per second, and nautical miles — units that the Apollo astronauts, who had mostly trained as jet pilots, would have been accustomed to using. So, a man weighing 90kg would give his weight as lbs in the US and just over 14 stone in the UK.

Stone, British unit of weight for dry products generally equivalent to 14 pounds avoirdupois 6. The stone is still commonly used in Britain to designate the weights of people and large animals.

Three-stone weakling. One stone is 14 pounds; Three stone would be 42 pounds.

Scaling the unit up or down when reporting measurements is good practice because: It can be used to keep the numeric value of measurements to reasonably-sized numbers, say between values of 0. It can be used to remove ambiguous place-holding zeroes in measurments, so that the number of significant figures are properly represented. The prefixes instantly convey how many decimal place moves are required of the numeric value.
