The app is developed by Abiro, sporting many of the conversions available at onlineconversion.com, as well as custom conversions and formula calculations. More below.

Abiro Converter supports many common and not so common conversions (more than 1700, in large part from onlineconversion.com), 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, 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 bugs, please contact us via support@abiro.com. Also feel free to check out our site at abiro.com.

**Conversion**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**Values can be entered with "." or "," as decimal point, yet results will always be shown with ".".

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
