I'm looking for the most applicable terminology for defining the scale of measurement units in a particular system.
For example, for a distance, in 'metric', the 'small' scale could be 'm' and the 'big' scale could be 'km'. In 'imperial', the 'small' scale could be 'feet' and the 'big' scale could be 'miles'.
Similarly with a speed, the 'small' and 'big' scales could be 'm/s' and 'km/h' respectively for the metric system, and 'ft/s' and 'mph' respectively for the imperial system.
Throughout this post I've referred to a 'small' and 'big' 'scale'. Are there better terms I could use?
