A LITTLE CONTEXT

Know what you’re calculating.

Choose a tool, enter your numbers and get an instant result.

How it works

Inches = centimeters ÷ 2.54. Convert length, width and height separately, keeping the L × W × H order.

25.4 × 50.8 × 76.2 cm = 10 × 20 × 30 in

Can I use these results in a listing?

Yes. Copied dimensions and product specifications include units. Decimal places affect display only. Check source measurements and units before publishing.

Do I need an account?
