Formula for Calculate the weight of steel pipe
| psi = Mpa*145.0377 | kgs = lbs*2.20462 | ||
| ksi = psi/1000 | lbs = kgs/2.20462 | ||
| °F = (°C*1.8)+32 | m = ft*0.3048 | ||
| °C = (°F-32)/1.8 | ft = m/0.3048 | ||
kg/m (CS/AS) = [OD(มม)-WT(มม)]*WT(มม)*0.0246615
kg/m (SS) = [OD(มม)-WT(มม)]*WT(มม)*0.02491
