Example

6'2" will be replaced with 6'2" (187.96cm)

Unit support

For now it supports the following conversions:

  • Feet + inches to cm or m
  • Lbs to kg
  • Miles to km
  • Miles per gallon to litres per 100 km
  • Miles per hour to KM/H
  • Time 1/21/16 1pm to 21.01.2016 13:00

Bookmarklet

If you don't use Safari, the code still works as a bookmarklet. Created using bookmarkleter

Paste the following as your bookmark URL:
