Frequently Asked Questions

1 What is the difference between weight and mass?
In everyday use, weight and mass are often used interchangeably. Technically, mass is the amount of matter (measured in kg, g), while weight is the force of gravity on that mass (measured in newtons). For practical purposes, this converter treats them the same, which is standard for most applications.
2 How accurate are the conversions?
All conversions use precise conversion factors. For example, 1 pound = 0.45359237 kilograms exactly. Results are displayed with up to 4 decimal places for accuracy while remaining readable.
3 Can I convert between metric and imperial units?
Yes! The tool seamlessly converts between metric units (kilograms, grams, milligrams, tons) and imperial units (pounds, ounces). You can convert from any unit to any other unit.
4 What is a metric ton vs a US ton?
A metric ton (tonne) equals 1,000 kilograms or 2,204.62 pounds. A US ton (short ton) equals 2,000 pounds or 907.185 kilograms. This converter uses metric tons. For US tons, convert to pounds first (1 US ton = 2,000 lbs).
5 How do I convert recipe measurements?
Enter the weight from your recipe, select the source unit, choose your preferred unit, and the tool converts instantly. For example, convert 500g to pounds for US recipes or 2 lbs to kilograms for metric recipes.
