Online Weighing Scale Reader is a free physics simulator based on a code written by Loo Kang WEE and Félix Jesús Garcia Clemente. It allows you to simulate an open source physics and measure masses. It is a scale model simulator that lets you test what you have learned by trying the input field.

It is based on an open source physics code, which allows you to set the masses, their divisions and units. You can set the mass and division of the scale, but also the precision, the input field and the output field.

The mass is measured in grams and kilograms. The precision is measured in g and kg. The decimal places can be set from 0 to 6.
