WebbA "gram" is the standard unit for mass. "Kilogram" is just 1 000 x the mass of the gram. To multiply by 1 000, all you have to do is move the decimal point to the right 3 times because there are 3 zeros, and to divide by 1 000 you move it 3 times to the left. For example: 3 kilograms = 3 000 grams 3 grams = 0.003 kilograms WebbThe unit of substance in the FPS system is the pound-mole (lb-mol) = 273.16 × 1024. Until the SI decided to adopt the gram-mole, the mole was directly derived from the mass unit as (mass unit)/ (atomic mass unit). The unit (lbf⋅s 2 /ft)-mol also appears in a former definition of the atmosphere. lowest price led shop light
