There are two types of unit converters: compact style and expanded style. The compact-style converter converts one unit of measurement into another unit of measurement while the expanded-style converter converts one unit of measurement into several different units of measurement.

How to use the compact style converter

Select the unit to convert from in the input units list, input its value in the corresponding input box and select the unit to Converter to in the output units list. The conversion result will immediately appear in the output box and in the results box.

How to use the expanded style converter

Choose the unit to convert from and type the value (for example, "1"). Our conversion engine will return a list of other units with the appropriate converted values.

Helpful hints

You can sort the units alphabetically or by popularity, switch between compact and expanded view using the converter control panel which is at the top of each converter specific page, just below the site navigation panel.

Operations

Our converters support the use of mathematical expressions as well as simple values as input data for conversion. The following is a lists of supported basic operators, advanced operators, and constants.

The following table lists basic functions built into the converters:

Operator	Meaning	Example
+	addition	12+34
-	subtraction	5.6-7.8
*	multiplication	5.5*110
/	division	128/5
%	modulo (finds the remainder after division)	14%2
()	Forces the expression within the parentheses to be calculated first, overriding the normal order of operations	2*(3+4)

The following table lists advanced functions and constants built into the converters:
