The formula used to calculate the weights shown is:
  Pounds per foot (lb/ft) = 10.9953(D-t)t
      Where:       D = Outside diameter (O.D.) (inches)
                          t = Nominal wall thicness (inches)

 

1 Conversion factor to determine the approximate weight in kilograms per meter:
    1 pound per foot (lb/ft) = 1.49 kilograms per meter (kg/m)

2 Birmingham Wire Gauge (BWG)

Notes:

  1. All tubing is produced in 17 to 24 feet (5.1 to 7.3 m) standard random mill lengths (additional lengths available upon request)
  2. Cut-to-length and deburring available.
  3. Additional diameters and wall thicknesses available upon request.
  4. Metric sizes also available.
  5. Tubing will be bundled or packaged in U-Channel boxing for shipment (additional packaging available upon request).
  6. Minimum order quantities apply.

 

To determine the approximate weight in pounds per foot (lb/ft) ¹ for other alloys, multiple the value shown in the Tube Sizes & Gauges chart (above) by the applicable conversion factor in the Tube Weight Conversion Factors chart (below).
