Conversion

Convert torr to atm or atm to torr. Check the conversion factor and see whether pressure is above or below 1 atm.

Calculate mechanical horsepower from torque and RPM, or find matching torque or RPM at the same operating point.

Convert psi, bar, kPa, Pa, atm, mmHg, inHg, and more. Check gauge, absolute, and differential pressure references.

Convert Nm to in-lbs or in-lbs to Nm fast, with exact results, tool-friendly rounding, and a clear warning about in-lbs vs ft-lbs.

Convert torque between Nm and ft-lb, see the exact result, and get a practical rounded wrench setting fast.

Convert torque to N*m, lb-ft, and lb-in. You can also calculate torque, required force, or lever-arm length.

Convert lbs to newtons or kilonewtons, with clear lbf vs lbm guidance and optional gravity for weight calculations.

Convert torque between in-lb and ft-lb fast, with a clear direction switch, rounding control, and simple wrench-setting notes.

Convert inch-pounds and newton-meters fast, with exact results and an optional rounded wrench setting for real tool use.

Convert force units like N, lbf, kgf, dyn, and kN fast, with optional all-units results and a note to avoid mass vs force mix-ups.
