Formulas

  • Weight of Squares/Rectangles = 0.284 x thickness x width x length
  • Weight of Circles = 0.892 x thickness x (diameter / 2)2
  • Weight of Rings = 0.223 x thickness x (OD2 - ID2)
  • Diagonal of a Rectangle or Square = the square root of (w2 + L2)

Conversion Factors

Length

  • 1 m = 39.37 in = 3.28 ft = 100 cm
  • 1 ft = 30.48 cm
  • 1 in = 2.54 cm
  • 1 mi = 5280 ft = 1.609 km
  • 1A = .00000001 cm
  • 1 micron = .0001 cm = .000001 m

Mass

  • 1 slug = 14.59 kg = 32.2 lb (mass)
  • 1 g = .001 kg = .0000685 slug

Time

  • 1 year = 365 days = 31,600,000 sec
  • 1 day = 24 hrs = 1,440 min = 86,400 sec

Area

  • 1 cm2 = 0.155 in2
  • 1 m2 = 10.76 ft2
  • 1 in2 = 6.452 cm2
  • 1 ft2 = 144 in2 = .0929 m2

Volume

  • 1 m3 = 1,000,000 cm3
  • 1 m3 = 1,000 liters = 35.3 ft3 = 61,000 in3
  • 1 ft3 = .0283 m3 = 28.32 liters

Velocity

  • 1 mi/hr = 1.47 ft/sec = 0.447 m/sec
  • 1 m/sec = 100 cm/sec = 3.281 ft/sec
  • 1 mi/min = 60 mi/hr = 88 ft/sec

Acceleration

  • 1 m/sec2 = 3.28 ft/sec2 = 100 cm/sec2
  • 1 ft/sec2 = 0.3048 m/sec2 = 30.48 cm/sec2

Force

  • 1 N = 100,000 dyne = 0.2247 lb

Pressure

  • 1 N/m2 = 10 dyne/cm2 = 0.000145 lb/in2

Energy and Power

  • 1 J = 10,000,000 ergs = 0.239 cal = 0.738 ft lb
  • 1 cal = 4.18 J
  • 1 hp = 745 W = 550 ft lb/sec
