Work out rough approximations of sizes and capacities of different things on site maps and areas.

The basic idea is to give you a quick drawing scratch pad that calculates the area and various capacities and resourcing requirements for what you colour in.

These calculators are only intended to be used for estimations and approximations. They should not be used for formal calculations, and are not guaranteed to be accurate. In particular, different devices may have unsupported DPI ratios which may lead to wildly inaccurate calculations. This app is not optimised for small phones and other small screen devices.
