Numbat is a scientific calculator and small scripting language that checks units and dimensions in every calculation. For example, you multiply a force by a distance and get the result in the right units, and if you try to add metres to seconds you get an error. Engineers use it for quick calculations and unit conversions without mistakes. It works in the browser and on the command line.
