### Grams to kilograms conversion explanation

Grams and kilograms are part of the International System of Units (SI). As part of SI, they use SI prefixes. SI prefixes indicate that a unit is a multiple or fraction of the unit the prefix is attached to. The same prefixes are used to indicate the same fractions or multiples. SI is a base ten system, meaning that prefixes indicate multiples or fractions of powers of 10.

The prefix "kilo-", denoted using the symbol "k" indicates 10^{3} or 1000, so:

1 kg = 1000 g

1 g = kg
