Convert it once, in the units your spec sheet uses.
Torque, force and pressure conversions plus cylinder force, air consumption and Cv flow calculations. Built for the moment you are comparing a tool specification against a joint requirement and the two are written in different units.

Reading the results
What the numbers assume.
Cylinder force
Theoretical force is bore area times working pressure. The effective figure applies your friction and seal loss percentage and then your safety factor, so it is deliberately more conservative than the catalogue figure for the same cylinder.
Air consumption
Usage is reported per minute at standard atmospheric conditions, ANR at 0 °C and 1.01325 bar. A double-acting cylinder subtracts the rod area on the return stroke, which is why the two directions do not consume the same volume.
Cv flow
Valve Cv calculations assume dry air with an adjustable temperature. Wet or lubricated air behaves differently and the result should be treated as an upper bound.
Torque and pressure
Straight unit conversion with no assumptions. Where a tool specification quotes a range, convert both ends; the useful comparison is whether your target sits inside the band, not near it.
Sizing a tool
The four numbers that decide the model
Fastener and joint, torque target and tolerance, cycle time and duty, and available air or battery supply.

What does the air consumption calculator assume?
Usage is reported per minute at standard atmospheric conditions (ANR, 0°C, 1.01325 bar), and a double-acting cylinder subtracts the rod area on the return stroke.
Is the cylinder force figure the number I should order against?
The “effective” figure already applies your friction/seal loss percentage and safety factor, so it is the more conservative number to size a tool or cylinder against. The “theoretical” figure is bore area times pressure with no margin applied.
