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 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 103 or 1000, so:

1 kg = 1000 g

1 g = kg
