For many transformations, particularly when automated, please use the udunits2 software where possible. For example, in R, you can use  ```  library(udunits2) ## transform meters to mm ud.convert(10, "m", "mm") ## equivalently, via the udunits synonym database ud.convert(10, "meters", "millimeters") ## it can also handle more complex units ud.convert(10, "m/s", "mm/d")```
