## User Guide

This online tool will calculate the pressure generated by a dead weight tester pressure calibrator by entering the total mass of added weights, the effective area of the piston-cylinder and the local gravity.

### Formula

The formula used by this calculator to determine the pressure generated by the dead weight tester is:

F = m · g

P = F / A

P = m · g / A

#### Symbols

- P = Pressure
- F = Force
- A = Area
- m = Mass
- g = Acceleration due to gravity

### Mass of Dead Weights (m)

Enter the total mass of weights added to the dead weight tester.

### Effective Area (A)

Enter the effective area of the dead weight tester, which you should find in the manufacturer’s documentation or instrument labelling.

### Local Gravity (g)

Enter the acceleration due to gravity for your geographical location in metres per second per second (ms^{-2}). The local gravity is dependent on several factors such as latitude, height above sea-level, local geological density, etc… Refer to your national geological survey data for your location or use this local gravity calculator to determine a close approximation. The default value is set to 9.80665 ms^{-2} which is standard gravity.

### Generated Pressure (P)

This is the pressure produced by a dead weight tester with the entered quantities for mass, area and gravity.
