Answer 2

Imperial standard of length:



The international yard is defined in terms of the metric system of units to be exactly 0.9144 metres. This definition was agreed upon by the US, Canada, the UK, South Africa, Australia and New Zealand in 1959. However, the US continued to use its previous national definition of the length units for surveying purposes.



metric system is incorrect terminology.



The International System of Units (abbreviated SI from the French Le Système International d'Unités) is the modern form of the metric system and is generally a system devised around the convenience of the number ten. It is the world's most widely used system of measurement, both in everyday commerce and in science.



Unit of length in SI system is the meter.

When will you lot change? Go metric, rejoin the world!
