How to convert grams to kilograms

These units measure mass. Pounds and ounces mean avoirdupois unless the unit explicitly says troy; a fluid ounce measures volume and requires a density to relate it to mass.

Formula
kg = g × 0.001

One gram is 0.001 kilograms, so a single multiplication converts any value.

Example
0.01 kg = 10 × 0.001

Sources and precision

Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
