Mass conversions are useful for material quantities, equipment weight, shipping weights, product specifications, laboratory measurements, agricultural inputs, food weights, and engineering calculations.
Use this converter when comparing metric, U.S. customary, imperial, scientific, and engineering mass units.
Your result shows the entered mass converted from the starting unit into the selected ending unit. The calculator also shows the conversion rate used so you can verify the calculation.
For engineering and material work, make sure the mass unit matches your data sheet, drawing, load table, shipping document, product label, or calculation sheet.
Mass is the amount of matter in an object. It is different from weight, which is the force caused by gravity.
The SI base unit of mass is the kilogram, abbreviated as kg.
One kilogram equals approximately 2.20462 pounds.
One ounce equals approximately 28.3495 grams.
This converter is designed for mass magnitude conversions, so it uses non-negative values.
