Mass conversion

There are two main unit systems for measuring masses, the Imperial System of Measurement and the Metric System of Measurement.

Most countries use the Metric System, which uses the gram as the basic unit for length measuring. The prefixes like kilo, milli and centi are used to count orders of magnitude of lengths.

The Imperial System is also called The British Imperial because it came from the British Empire. According to acting UK law each imperial unit is defined in terms of its metric equivalent. The metric system nowadays is in official use within the UK for most applications. But the use of imperial units is nevertheless widespread amongst the public, so it is important to know what are ounce or pound and how to convert these units to Metric System and vise versa.


Example 1: Convert 10 kg to lbs

First, select the appropriate units in the left and right parts of the calculator – “Kilogram” and “Pound”. Then just type 10 in the “Kilogram” field. The value in pounds (approx. 22.046) will automatically pop up in the “Pound” field.


Example 2: Convert 15 lbs to kg

Do exactly the same like in previous example, just type 15 in the “Pound” field. The value in kilograms (approx. 6.8) will automatically pop up in the “Kilogram” field.
