Frequently asked questions
Where does this come up when selling online?
Package dimensions for courier booking (usually cm on Indian platforms), product-size fields for international listings (often inches), and reading a size chart from an overseas brand or buyer.
Is this the same as the Dimensional Weight Calculator?
No. This converts a single length between units. The Dimensional Weight Calculator takes length, width and height together and works out the volumetric weight your courier bills you on.
