How to use this tool
- Enter a value and pick its unit. The table updates as you type.
- Read across the table for the same weight in each unit.
- Use Load sample to see 1 pound worked through.
Worked example
Enter 1 and choose Pounds (lb). The table shows 0.45359237 kilograms and 453.59237 grams — the exact international pound definition — plus 16 ounces, as expected.
What this tool does not do / Limits
This tool converts mass/weight units only, using the international pound (exactly 0.45359237 kg). It does not convert between weight and volume (that needs a density), and it does not distinguish the troy ounce used for precious metals from the avoirdupois ounce used here.
Frequently asked questions
What is the difference between a short ton and a long ton?
A US short ton is 2,000 pounds (about 907 kg); a UK long ton is 2,240 pounds (about 1,016 kg). A metric tonne is 1,000 kg, which is neither.
Is a kilogram a weight or a mass?
Strictly, a kilogram is a unit of mass; on Earth the two are used interchangeably in everyday language, and this tool follows that everyday use.
