Calculation working
- Result = input × source factor ÷ target factor
- 1 × 1 ÷ 0.001 = 1,000 g

Display: 10 significant digits. More digits do not make the original measurement more accurate.

Convert mass for material schedules, parcel labels, ingredient quantities and equipment datasheets.
Kilogram, pound and ounce here measure mass. The category's familiar name is Weight; it does not calculate gravitational force in newtons.
Check before using the result
- Ton means metric tonne: 1,000 kg. It is different from a US short ton or an Imperial long ton.
- Mass does not determine material volume without density. A kilogram of sand and a kilogram of water occupy different volumes.
Definitions and method: NIST: unit conversion factors and rounding. Calculations use double-precision arithmetic; the display precision can be adjusted above.
