I have 4 cells. Example:
A:1_Incehs
A:2 _Foot
A:3_Centimeters
A:4_Meters

I would like to be abele automatically to calculate (insert) the entire measurements unit from the table, if I insert any of them.
Let say, if I insert “3” for Meters to have automatically calculate all other. Or if I’m using “Inches” or “any other” to have automatically calculate the rest.

The same formula I would like to apply to Exchange Rates. Example:
US
CAN
EU

Any help on this would be greatly appreciated.
Thank you,
