OPie Unit Converter

OPie Unit Converter simultaneously converts 16 elements within the following categories: length, temperature, area, volume, weight, angle, digital storage, energy, pressure, force, time, electric current, speed, and luminance. Future updates will add new catagories. The OPie Unit Converter is also part of the OPie RPN Calculator (also available at the App Store).

Use the rotary selector (picker selector) to choose the category. Use the number buttons to input your desired value. Then press one of the input buttons.
