This calculator is to help you find the right length lever or weight to improvise a torque wrench. If you have a luggage/fish scale this could be used to apply to correct force on a known length lever to achieve a desired torque.

Instructions:
13
Step 1: To start, put a question mark in the cell for which you don't know the variable's value (Row 2).
14
Step 2: Enter the known values. For example, if the desired torque is known (2 Nm), and you have a single 5kg exercise weight with which to exert force, then enter these values into the top row. The calculator will then display the required length of lever in the corresponding colour in column B to achieve the desired torque.
15
Note: DO NOT EDIT CELLS B5:B7! The cell in the range B5:B7 with the same colour as your question mark will have an answer.
