Physics and engineering calculations were done in non-metric units in the past. In some areas they are still done that way, for example in the aerospace industry in the US. More than one such non-metric systems of units existed but I have no desire to spend my time teaching non-metric units. If you wish you could go to a public library or to the internet for such information.
