Titanium Weight Calculator
Enter the shape and size of the stock, choose the grade, and read the volume and weight straight off. Commercially pure titanium is calculated at 4.51 g/cm3 and Grade 5 at 4.43 g/cm3.
Dimensions in millimetres. The result is a theoretical weight for solid stock; cut stock runs slightly light and rolled tube slightly heavy against the nominal figure.
Which density does each grade use?
| Material | Density | Note |
|---|---|---|
| Titanium Grade 1-4 (CP) | 4.51 g/cm3 | Food contact, tableware, cookware, bottles |
| Titanium Grade 5 (Ti-6Al-4V) | 4.43 g/cm3 | Tools, fasteners, higher strength parts |
| Stainless steel 304 | 7.93 g/cm3 | Reference only, for the weight comparison |
| Aluminium 6061 | 2.70 g/cm3 | Reference only, for the weight comparison |
Why not calculate a cup or a pot this way?
A vessel is a thin shell, not a solid block. Running a 450 ml bowl through a solid-volume formula returns a number several times its real weight, because most of the volume is air. For finished pieces we publish the weight per SKU instead: a 450 ml bowl is 76 g at a 125 mm diameter, a 300 ml Sierra cup is 46 g at 126 x 45 mm, a 450 ml cup is 58 g, and a 750 ml bottle is 109 g.
235 of the 503 SKUs in the range publish a weight for exactly this reason. If the piece you are quoting does not publish one, ask us for it - a weight is a specification, not a favour.
How accurate is a theoretical weight?
Within a few percent for solid stock, and that is usually enough for a freight estimate or a material budget. It is not enough for a mill certificate: real weight depends on the actual chemistry, the rolling tolerance and the cut length. Use this page for planning, and the certificate for the paperwork.
