Force Converter

Convert between newtons, pounds-force, and other force units

How to use: Convert force measurements used in physics and engineering. Select from newtons (N), kilonewtons (kN), pound-force (lbf), kilogram-force (kgf), or dynes. Key conversions: 1 newton = 0.225 pound-force, 1 kilogram-force = 9.807 newtons. Common applications: structural engineering, mechanical design, physics calculations, load testing, and aerospace engineering. Force = mass × acceleration.

Pressure Converter

Convert between pascals, PSI, bar, and other pressure units

How to use: Convert pressure measurements for industrial, scientific, and everyday applications. Choose from pascals (Pa), kilopascals (kPa), megapascals (MPa), bar, atmosphere (atm), PSI (pounds per square inch), or mmHg. Reference values: Atmospheric pressure = 1 atm = 101.325 kPa = 14.7 PSI = 760 mmHg. Tire pressure typically 30-35 PSI. Essential for HVAC, hydraulics, pneumatics, weather forecasting, scuba diving, and medical equipment.

Torque Converter

Convert between newton-meters, foot-pounds, and other torque units

How to use: Convert torque (rotational force) measurements for automotive and mechanical applications. Choose from newton-meters (N⋅m), pound-feet (lbf⋅ft), pound-inches (lbf⋅in), or kilogram-meters (kgf⋅m). Key conversion: 1 pound-foot = 1.356 newton-meters. Common uses: engine specifications (typical car: 150-300 lb-ft), wheel lug nuts (80-100 lb-ft), bolt tightening specifications, and mechanical engineering. Critical for proper assembly and preventing over-tightening.
