• You can use any units in the Ready Reckoner Chart below—just make sure you use the standard abbreviations like cm, m, kg, lb, ft, inch, degC, etc. (not their plural forms).
• If you want to convert “feet” or “centimeters”, simply use ft or cm:
  • Type: 1 foot to cm
  • Or: 1 ft to cm
  • Not: 1 foot to cms (that will cause an error)
