Using this weight converter

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.
