This table lists units of measure of one category or more formally, units of the same dimension. Viewers should note that the values displayed may be displayed with reduced precision for legibility and ease of use and may therefore be approximate values only. For conversions with greater precision please use the interactive conversion tables.

The format of values are displayed in accordance with the format proposed by N.I.S.T., The National Institute for Standards and Technology, on their page titled "SI Unit rules and style conventions" Item No. #16, Digit Spacing where values are expressed as decimal values. Some values that are exact are more accurately expressed as fractions and it is left to the reader to make the required numerical approximation.

Registered users will avoid the display of randomly overwritten values e.g. "********". To register select 'Register' from the 'General' dropdown menu above.
