Pressure to Force Conversion Chart
The chart below is in “force”. Torque is typically measured in foot-pounds. In order to
calculate the torque, the length from the load pin to the pipe center must be known in inches.
The torque in food pounds can then be calculated by the formula:
Torque (foot-pounds) = Force (lbs) x Length (inches) / 12
