CommonUnits[{quantity1,quantity2,…,quantityn}]

converts quantity1 through quantityn to common units across compatible dimensions.

Details

  • CommonUnits will convert the input list's units to a common unit for each subset of input units with common dimensions.
  • CommonUnits uses heuristic methods to determine a unit that best fits the input data.
  • Operations involving currency units require internet connectivity.
