Enter the mass, choose the source unit and then the target. The swap button reverses the conversion. Everyday language usually says weight, while the converter technically handles units of mass.
Kilograms, pounds and ounces
One pound contains 16 ounces. For a combined value such as 8 lb 4 oz, convert ounces to pounds first: 4 ÷ 16 = 0.25 lb, then enter 8.25 lb. In the other direction, multiply the fractional pound by 16.
Stone, carats and tons
Stone is commonly used for body weight in the British context and equals 14 pounds. A carat is a small mass unit used for gemstones. The options explicitly distinguish metric tonnes from US short tons.
Choose useful rounding
For example, 70 kg is about 154.32 lb. One or two decimal places are often enough for everyday or shipping use; technical follow-up calculations should avoid rounded intermediate values. Very small and large values are supported while the result remains representable.
