How many grams make a kilogram?
1,000 grams (g) = 1 kilogram (kg) 2,070 grams = 2.07 kgs – all you need to do is place a decimal point after the thousandth which is 2 in this case making it 2.070 which is 2.07 kgs (always drop the zero if it is at the end). If you had 42070 grams then that would be 42.07. Place the decimal point after the thousandth, which if you like is before the third number from the right, which is the zero.
Kilo stems from the Greek chilioi meaning “a thousand.” Therefore a kilogram is a thousand grams. Kilogram = 1,000 grams 1,000 grams/kilogram = 1 (ordinary algebra) You can divide anything by one without changing its value. Therefore: 2,070 grams/(1,000 grams/kilogram) = 2.070 kilograms Notice that grams cancel out and kilogram is left in the numerator of the answer. Engineers often use “division by one” to make conversions of units in complex identities. It is a useful tool to learn.
