This is a small app which makes it very easy to look up values in tables (math etc) when you have to interpolate both in two and in three rows. No more need for a calculator to interpolate manually. This app was designed primarily for cargo surveyors working with tank calibration tables, but the app does have its application in any environment where tables are used. As of 13th January 2015, this app has become FREE until further notice.
Linear Interpolation Master
This tool simplifies linear interpolation calculations for industrial commissioning engineers. It features large, easily readable numbers for field use and allows for quick swapping of coordinate systems, such as converting between 4-20mA and 0-100% scales.
- Large number display for field visibility
- Quickly swap X and Y coordinates
- 4-20mA to 0-100% conversion
- 0-100% to 4-20mA conversion
