Calculations

Where:

W = Plain end weight (lbs/ft)
t = Wall thickness (inches)
OD = Outside diameter (inches)

 

Lenghts, Sizes and Weights

OD in inches = Millimeters / 25.4
OD in millimeters = Inches * 25.4
Length in feet = Meters * 3.281
Length in meters = Feet / 3.281
Weight in metric tons = Net tons / 1.1023
Weight in net tons = Metric tons * 1.1023

Temperature

°C = 5/9 (°F-32)

Conversions

1 inch (in.) = 25.4 millimeters (mm) exactly
1 square inch (sq.in.) = 645.16 square millimeters (mm2) exactly
1 foot (ft.) = 0.3048 meters (m) exactly
1 pound (lb.) = 0.454 kilograms (kg)
1 pound per foot (lbs./ft.) = 1.4895 kilograms per meter (kg/m)
1 pound per square inch (psi) = 0.006895 Megapascals (Mpa) for stress
1 foot-pound (ft-lb.) = 1.355818 Joules (J) for impact energy
1.355818 Newton-meters (N.m) for torque
1 metric ton = 2204.6 pounds
1 net ton = 2000 pounds
1 short ton = 2000 pounds
1 long ton = 2240 pounds
