A pound in grams
1 avoirdupois pound is exactly 453.59237 grams. It contains 16 avoirdupois ounces.
Weight Converter
This converts mass, commonly called weight. Pounds and ounces mean avoirdupois unless marked troy. Mass does not depend on local gravity.

Display rounding does not change the calculation. Scientific notation keeps very small values visible; extra digits do not add measurement accuracy.

How to use the Weight Converter
- 01
Enter a numeric value without a comma separator or unit suffix, then choose the source and destination units.
- 02
Read the main result and equivalent-unit table. Choose 3, 6, 9, or 12 significant digits for display; calculation constants are not rounded to match the display.
- 03
Use the shipment mass from matching packages panel for the practical calculation. Restore its example independently from the converter.
- 04
Copy the conversion or task results, or download the displayed conversion table as a CSV. Clear removes the converter value.
Examples
Three different tons
1 metric tonne is 1,000 kg. A US short ton is 907.18474 kg; a UK long ton is 1,016.0469088 kg. Choose the definition shown on your document.
Mass and force use different units
Mass is measured in kilograms or pounds of mass. Weight as a physical force equals mass times gravitational acceleration and is measured in newtons or pounds-force. Use the Force Converter for that calculation.
Ounces need a definition
The common avoirdupois ounce is 28.349523125 grams. A troy ounce, often used for precious-metal mass, is 31.1034768 grams. The troy option is separate, and the pounds option is always avoirdupois.
Precision and accepted input
Use a decimal point or scientific notation such as 1e3. Blank values, unit suffixes, separators, and nonfinite numbers are rejected. Input magnitudes above 1e100 or nonzero magnitudes below 1e-100 are outside the supported range. The table rounds only for presentation, so 12 displayed digits should not be interpreted as 12 digits of measurement accuracy. Binary floating-point calculations can differ from exact decimal arithmetic in the final digits.
What to know
- No carats, slugs, density conversion, or shipping charge estimates.
- A converted mass does not determine load safety or lifting capacity.
Common questions
What does stone mean?
One stone is 14 avoirdupois pounds, exactly 6.35029318 kilograms. Decimal stone is a fraction of a stone, so 10.5 stone equals 10 stone 7 pounds.
Which ton should I choose?
Use metric tonne for 1,000 kg, US short ton for 2,000 lb, or UK long ton for 2,240 lb. A document saying only “ton” is ambiguous.
