Welcome to Abiro Converter!


Abiro Converter supports many common and not so common conversions (more than 1700), as well as basic mathematical operators and calculation of formulas enabling use as a basic calculator as well. You can also create your own conversions via Custom, that way extending the range of Converter's capabilities to whatever might fancy you.

We hope you'll like it, and if you have ideas for improvements or find errors, please contact us via [email protected]

(this information is also available in the app.)


You convert values in a few easy steps:

Select a Category (except time (advanced) and custom; see more below).
Select From and To units. Any combination will work.
Enter a value in Result.
Select Convert to perform the conversion.
Possibly use operators on the Result and Operand.


Values are entered and shown with "." as decimal point.

"," will be used as thousands separator if that setting is activated.

When Notation is set to scientific or engineering, 10-exponent will be shown as "E" (e.g. "1E-4", meaning "1 times 10 to the power of -4"). You can also enter values using "E" or "e".

If an error occurs status will be shown above Convert. Press Clear to reset or make a new conversion or calculation.

Time (advanced)

Select Category time (advanced).
Enter Hours, Minutes and/or Seconds.
Select Convert to perform the conversion to decimal.
Possibly use operators on the Result and Operand.
Custom conversions

Creating/editing custom conversions

Click on Custom.
Click on New to create a new custom conversion.
Enter a descriptive Name, choose what Operator to use and enter the Operand for the conversion.
In the case of f(x) you enter a formula in the Operand field. Read about use of f(x) under Formula below.
Click Save to save the conversion.
Click the Back button to get back to the main screen.
You Edit or Delete a conversion by selecting it in the list and clicking the appropriate button.

Note that you can change any of the values for a conversion when editing, including the name. The list of custom conversions is sorted on the name.

Settings are saved persistently.

Using custom conversions

Select Category custom.
Select one of the previously defined custom conversions.
Enter a value in Result.
Select Convert to perform the conversion.
Possibly use operators on the Result and Operand.


+: adds Operand to Result
-: subtracts Operand from Result
×: multiplies Operand with Result
÷: divides Result with Operand
1/x: performs inversion of Result
x²: performs square on Result
√x: performs square root on Result
xⁿ: performs Result to the power of Operand
Swap: exchanges the selected units
f(x): Treats Operand as a formula; see more below
Custom: configures custom conversions
Clear: resets all value fields


Settings: configures the application settings; see more below
Help: is what you read right now
About: provides information about the application and its provider


Precision: how many digits should be shown after the decimal, whatever the notation; the result will be rounded at that point; practical maximum is 16
Thousands separator: Sets whether "," should be shown for each thousand multiple in normal notation
Notation: what notation to use for results: normal (no 10-exponent), scientific (10-exponent) or engineering (10-exponent in 1000s)
Notation threshold: at what point (10^threshold or 10^-threshold) scientific or engineering notation should kick in
Default value: what value to show in the Result field after a Clear

This applies to f(x) on the main screen and in Custom. In both cases the formula is entered in respective Operand field.

The input value (Result) is expressed as 'x' in the formula, e.g. 'sin(x)+x/2'. The result is shown again in Result to simplify accumulative calculations and conversions.

Keywords: conversion, unit, formula, calculation

Revised My earlier review was harsh. Author, while conscientious and ambitious, was perhaps inexperienced. Do be careful not to repeat a conversion unintentionally. Haven't used this for a while, but IIrc it has oodles of obscure and historic units, which would be very valuable for scholars.
