Fix prefix abbrevs (#421)

Fixes several wrong abbreviations.
Removes redundant prefix abbreviations (`k`, `M` etc is prefixed by default for kilo, mega etc.)

#### Breaking changes
GigabritishThermalUnit: `mmBTU` => `GBTU`
MegabritishThermalUnit: `mBTU` => `MBTU`
Kilopound: `KLbs` => `klb` (neither is commonly used)
Megapound: `MLbs` => `Mlb` (neither is commonly used)
