Weight Converter
Our Weight Converter makes it easy to convert a weight or mass measurement from one unit to another. Enter a value, choose the starting unit, select the unit you want to convert to, and the calculator provides the converted result instantly.
What Is a Weight Converter?
A Weight Converter is an online tool used to convert measurements between commonly used weight units. It is helpful when a measurement is given in a unit that is unfamiliar or different from the unit you need.
Common units include kilograms, grams, milligrams, pounds, ounces, stones, and metric tonnes. The exact units available depend on the converter.
How Does the Weight Converter Work?
The converter uses standard relationships between measurement units. When you enter a value and select the units, the calculator applies the appropriate conversion factor and returns the equivalent measurement.
For example, to convert kilograms to pounds, the standard relationship is:
1 kilogram = 2.2046226218 pounds
Therefore, if you want to convert 10 kilograms to pounds:
10 Γ 2.2046226218 = 22.0462 pounds
So, 10 kilograms is approximately 22.05 pounds.

Popular Weight Units
Kilogram (kg)
The kilogram is the base unit of mass in the International System of Units (SI). It is commonly used for body weight, products, and larger everyday measurements in many countries.
Gram (g)
A gram is a smaller metric unit commonly used for food, ingredients, and other relatively light objects. One kilogram contains 1,000 grams.
Milligram (mg)
A milligram is one-thousandth of a gram and is commonly used for very small quantities.
Pound (lb)
The pound is widely used for measuring body weight and other everyday weights in the United States and some other countries.
Ounce (oz)
An ounce is a smaller unit in the imperial and U.S. customary systems. There are 16 ounces in one avoirdupois pound.
Stone (st)
A stone is a unit commonly associated with body weight in the United Kingdom and Ireland. One stone equals 14 pounds.
Weight vs. Mass
In everyday conversation, the words "weight" and "mass" are often used interchangeably. In physics, however, they describe different concepts. Mass measures the amount of matter in an object, while weight is the force produced by gravity acting on that mass.
Most everyday weight converters are designed for practical mass conversions, such as kilograms to pounds or grams to ounces.
Why Use a Weight Converter?
Converting measurements manually can be inconvenient, especially when working with unfamiliar units or decimal values. A converter provides the equivalent measurement quickly and reduces the chance of arithmetic mistakes.
- Convert kilograms to pounds and pounds to kilograms.
- Convert grams to kilograms or milligrams.
- Convert pounds to ounces.
- Convert stones to pounds or kilograms.
- Compare metric and imperial measurements.
- Work with decimal weight values without manual calculations.
Example: Pounds to Kilograms
Suppose you have a weight of 150 pounds and want to convert it to kilograms. Since one pound is approximately 0.453592 kilograms:
150 Γ 0.453592 = 68.04 kilograms
Therefore, 150 pounds is approximately 68.04 kilograms.
Example: Grams to Pounds
To convert 1,000 grams to pounds, first note that 1 kilogram equals 1,000 grams and approximately 2.20462 pounds.
Therefore:
1,000 grams = 1 kilogram β 2.20462 pounds
The converter can perform this calculation automatically when you select grams as the starting unit and pounds as the target unit.
Important Note
Conversion results are based on standard unit relationships. Results displayed with decimal places may be rounded for convenience, so small differences can occur when comparing rounded values with calculations using the full conversion factor.
