🧮 Conversion Formulas

Pressure (PSI to kPa)

kPa = PSI × 6.89476
Example: 100 PSI = 689.476 kPa

Force (kN to lbf)

lbf = kN × 224.809
Example: 10 kN = 2,248.09 lbf

Volume (m³ to ft³)

ft³ = m³ × 35.3147
Example: 1 m³ = 35.3147 ft³

Temperature (°C to °F)

°F = (°C × 9/5) + 32
Example: 20°C = 68°F
