How to use unit converters
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.
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.
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:
|%||modulo (finds the remainder after division)
|()||Forces the expression within the parentheses to be calculated first, overriding the normal order of operations
The following table lists advanced functions and constants built into the converters:
|pow||exponentiation (raise to a power of)
|sin, cos, tan||trigonometric functions (numbers are assumed to be radians)
|asin, acos, atan, atan2||inverse trigonometric functions
|log||logarithm base e
|exp||e raised to a power
|abs||the absolute value
|round||round to the nearest integer
|ceil||the smallest integer greater than or equal to
|floor||the greatest integer less than or equal to
|max||the greater number
|min||the lesser number
|e||mathematical constant e, the base of natural logarithms, approximately 2.718
|pi||the ratio of the circumference of a circle to its diameter, approximately 3.141592653589793
|ln2||the natural logarithm of 2, approximately 0.693
|ln10||the natural logarithm of 10, approximately 2.302
|log2e||the base-2 logarithm of e, approximately 1.442
|log10e||the base-10 logarithm of e, approximately 0.434
|sqrt1_2||the square root of 0.5, or one divided by the square root of 2, approximately 0.707
|sqrt2||the square root of 2
