Tips for using Unit Converter

Write down the original value with its unit before converting. Check that the result changes in the expected direction: one metre becomes a larger number when expressed in millimetres. Treat the illustration as a sense of scale rather than an exact equivalent.

Important limitations

Visual comparisons are approximate illustrations, not precision measurements. Check the selected units and the precision needed for technical work before using a result.
