Document Summary
Critical international system of units: o: the standard came out in 1960 called le systeme international d"unites. It was based upon 7 base units: mass = kilograms. Length = meters: time = seconds, kalvin = temperature, candela = light, mole = amount of substance, ampere = electricity. The difference between mass and weight iswhen describing weight you are talking about the force that is acting upon the object. Length used to be based on parts of the body (i. e. foot) British came up with imperial units through the british weights and imperial act in 1824. They tried to break down each measurements into smaller parts--1 mile, 8 furlongs, 10 chains, 22 yards, 3 feet, 12 inches. This was a very complex and made measuring difficult. From here we simplified this to come up with the critical international system of units (si units): 1km, 1000m, 100cm, 10mm, 1000 micrometers, When converting from american imperial units: miles to km = 1. 61 o.
