Questions

Frequently asked questions

How do I go from inches back to centimeters?

Put inches on the input side and centimeters on the other. The two menus are independent, so either unit can be the one you start from.

Is my measurement sent anywhere?

No. The conversion is arithmetic done by the page itself. Nothing you type is posted, logged or stored, and closing the tab clears it.

Why is the last digit different from my calculator?

The figure is rounded so it stays readable. A calculator carrying more decimal places can land on a different final digit for the same conversion.

Can I convert other lengths in the same panel?

Yes. Both unit menus in the length category hold the full list, so the panel is not limited to centimeters and inches.

Background

Working with centimeters and inches

Set the category to length, put your centimeter figure in, and choose inches on the other side. The number and the formula behind it appear straight away. The whole thing happens in this tab.

  • Centimeters and inches are both length units, so the conversion is a single factor rather than a scale shift.
  • The two unit menus are set separately, which is what lets the conversion run either way.
  • Rounding is applied to the displayed figure, so treat the last digit as approximate.
  • Switching the category changes both menus, which is how the same panel covers weight or volume.
