Useful Conversion Factors
Length. SI unit: meter (m)
Energy. SI unit: joule (J)
1 km = 1000 m = 0.62137 mi
1 J = 1(kg.m2)/s2 = 0.23901 cal
1 mi = 5280 ft = 1760 yd = 1.6093 km
1 cal = 4.184 J
1 m = 100 cm = 1.0936 yd
1 eV = 1.602176 × 10-19 J
1 in = 2.54 cm
1 MeV = 1.602176 × 10-13 J
1 cm = 0.39370 in
1 kWh = 3.600 × 106 J
1 Angstrom = 10?10 m = 100 pm
1 Btu = 1055 J
Mass. SI unit: kilogram (kg)
Pressure. SI unit: pascal (Pa)
1 kg = 1000 g = 2.2046 lb
1 Pa = 1 N/m2 = 1 kg/(m.s2)
1 lb = 16 oz = 453.59 g
1 atm = 101325 Pa = 1.01325 bar
= 760 mm Hg = 14.70 lb/in2
1 oz = 28.35 g
1 bar = 105 Pa
1 ton = 2000 lb = 907.185 kg
1 metric ton = 1000 kg = 1.102 tons
1 u = 1.66054 × 10-27 kg
Temperature. SI unit: kelvin (K)
Volume. SI unit: cubic meter (m3)
0 K = ?273.15 °C = ?459.67 °F
1 L = 10-3 m3 = 1 dm3 = 103 cm3 = 1.0567 qt
K = °C + 273.15
1 gal = 4 qt = 3.7854 L
°C = 5/9 (°F ? 32)
1 cm3 = 1 mL
°F = (9/5 °C) + 32
1 in3 = 16.4 cm3
