About These Converters
Each converter on this site uses a base-unit method: every measurement is first converted
to a common base (meters for length, grams for weight, milliliters for volume, etc.), then
converted to the target unit. This guarantees accuracy across all unit pairs without
maintaining a conversion table for every possible combination.
For temperature, which uses non-linear (offset) formulas, all conversions route through
Celsius as the intermediate unit. For data storage, the binary standard (1 KB = 1,024 bytes)
is used, consistent with how operating systems report file and disk sizes.
Results update instantly as you type. The full conversion table shows your input expressed
in every available unit simultaneously — useful when you need to compare across multiple
units at once.
