Just plug your numbers in at the top and spin the dials. How easy is that?

Convert kilograms into pounds and litres into cups. Convert miles into kilometres and metres per second into knots. Even convert miles into light years and picometres into angstroms. Do you work with other parts of the world and would like to easily calculate local units to foreign ones? Metrebug will help.

Metrebug has been around since 2010. It was the very first app created by ExtremeBytes Software.

We made the very hard decision to retire Metrebug, but want to say thank you to everyone who used and enjoyed Metrebug through all of these years.

How to use it

Put the number you want to convert in the entry space at the top. Spin the two dials on the left to form the unit you are converting from. Example: K (for kilo) and then metre to make kilometre. Then spin the two dials on the right to form the unit you are converting to. Example: -- (for no prefix) and mile. The conversion will show up at the top of the screen (next to your entry number).

You can then click the folder icon in the top right corner to save your conversion to your Favorites folder.
