Kilograms to Grams
The kilogram is the SI base unit of mass, defined today by the fixed value of the Planck constant. A gram is one thousandth of a kilogram, used for cooking ingredients and other small everyday objects. 1 kg equals 1,000 g, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to mass, measured here against mass's base unit (kg) — every other mass unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
g = kg × 1,000
kg = g × 0.001
Worked example: 5 kg × 1,000 = 5,000 g.
