CONVERSION FACTORS
(1) Length 1 inch
1 foot = 2.54 cm
1 yard = 30.48 cm
1 meter = 91.43 cm
1μ (micron) = 100 cm = 3.26 feet = 39.37 inches
= 3.281 × 10–6 ft = 0.0001 cm(2) Area 1 m^2 = 100 × 100 cm^2
(3) Weight 1 ton = 1.016 tonnes
1 kg = 2.204 lb
1 lb = 453.6 gm(4) Volume 1 cu.ft = 0.0283 cu.m
1 cu.in = 16.39 cu.cm(5) Density 1 kg/m^3 = 0.062 lb/ft^3
1 lb/ft^2 = 16.02 kg/m^2(6) Work, Energy 1 joule = 1 Nm
= 1 watt-sec
= 2.7778 × 10– 7 kWh
= 0.239 cal
1 cal = 4.184 joule
= 1.1622 × 10– 6 kWh
1 kWh = 8.6 × 10^5 cal
= 3.6 × 10^6 joule
1 kgfm = (1/427) kcal
= 9.81 joule(7) Force 1 Newton = 1 kg-m/sec^2
= 0.012 kgf
1 kgf = 9.81 N(8) Pressure 1 bar = 750.06 mm Hg
= 0.9869 atm
= 10^5 N/m^2
1 N/m^2 = 1 Pascal
= 10– 5 bar
= 10– 2 kg/m-sec^2
