Titanium bar

How to calculate the weight

The weight of round bar is easily calculated. Simply multiply the appropriate alloy density by the length and diameter multiplied by two of the required part (see worked example below).

Metric density (g/cm³) x x L x π / 4000 = weight
Example: 4.5 g/cm³ x 20 mm² x 1m x π / 4000 = 1.41 kg
 
Imperial density (lbs/in³) x x L x π / 4   weight
Example: 0.163 lbs/in³ x 0.75in² x 12in x π / 4 = 0.864 lbs


For imperial weight calculations certain measurements (fractions) need to be converted to decimal inches.

For an accurate calculation it is also important to allow for the rolled/drawn tolerances on section defined by the manufacturing specification please contact us for details.

Density of titanium

The acknowledged density of titanium is 4.50 g/cm3 (0.163 lbs/in3). Depending on the alloy elements added to manufactured specifications this can vary between 4.4 and 4.9 g/cm3 (0.159 and 0.177 lbs/in3).
