# Scaler with Automated Unit Conversion

## Description

On a drawing, some dimensions (actual size) are giving. How do we estimate the unknown ones? Eg:

The bed actual length is a0 = 6'-6", its tape measurement reading on its print is M0 = 5.24;

How do we estimate the room's actual length a1?

Using the same tape, its reading is M1 = 9.26.

Then we can calculate to estimate:

a1 = M1 * a0 / M0 = 137.84"

This is slightly different from the actual length of 139.5". In many cases, this can be sufficient.
