How to convert kilograms to grams
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.
g = kg × 1000One kilogram is 1000 grams, so a single multiplication converts any value.
10,000 g = 10 × 1000Kilograms to grams conversion table

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.
