### Common Converters

UnitConversion.org is the ultimate resource for unit conversion. Use its free online unit converters to easily convert between different units of measurement.

The converters support expressions such as the input string * "1+2*(3+5)"* involving not only basic mathematical operations,
but also advanced operations such as

*etc. So the calculators can solve not only unit conversions but math problems involving basic arithmetic and more complicated math.*

**sqrt, pow, sin, cos, abs,**Also, the converters seem to be the only ones (to the best of our knowledge) which feature custom handling of all
math-related operations involving conversions. The visible result is that, for example, you'll never see numbers like
* 4.999999* instead of

*or*

**5***instead of*

**4.0000001***when*

**4***and*

**5***are the correct conversion results. The inputted strings are automatically re-evaluated with every new symbol you type, so there is no need for a separate "Calculate" type button thus saving time.*

**4**Sometimes you've got an answer that looks like this * "4.12e+04"* or like this

*. The*

**"3e-08"***stands for exponent. So*

**"e"***is a convenient way of saying*

**4.12e+04***, or*

**4.12*104***. If your result was, for example,*

**4120000***, then the answer would have been*

**3e-08***, or*

**3*10-8***. (Read more about mathematical operations.)*

**0.00000003**Together with some common converters our website presents those categories of converters which will be useful for any engineer engaged in testing of prospecting, exploratory and development wells, and who carry out hydrodynamic and geophysical research works.

To work with all converters simply select the unit to convert * From* in the input units list. Select the unit
to convert

*in the output units list. Enter the value to convert from into the input box on the left. The conversion result will immediately appear in the output box.*
