Useful Conversion Factors

Temperature

  • K = °C + 273.15

  • °R = °F + 459.67

  • °F = 1.8 × °C + 32

  • °C = (5/9) × (°F − 32)

  • Δ °C = (5/9) × Δ °F

Mass

  • 1 kg = 1000 g = 2.2046 lbm

  • 1 metric ton = 1000 kg

  • 1 lbm = 453.59 g = 0.45359 kg

  • 1 short ton = 2000 lbm

  • 1 long ton = 2240 lbm

Length

  • 1 m = 3.2808 ft = 100 cm = 39.37 in

  • 1 μm = 1 micron = 10−6 m = 10−3 mm = 10−4 cm

  • 1 Å = ...
