kjer je:
Moč motorja
Velikokrat se uporablja drugačna enota, grami na [[kilovatna ura|kilovatno uro]]
▲Moč motorja merimo z [[dinamometer|dinamometrom]]. Enote za BSFC so [[gram]] /[[joul]] (g/J)
▲Velikokrat se uporablja drugačna enota, grami na [[kilovatna ura|kilovatno uro]] (g/kWh). Enačba za preračun:
▲:BSFC [g/kWh] = BSFC [g/J]×(3.6×10<sup>6</sup>)
▲Za spreminjanje med imperialnimi in metričnimi enotami uporabimo:
: BSFC [
▲:BSFC [lb/KM·h] = BSFC [g/kW·h]×0.001644
BSFC je tudi odvisen ob od vrste goriva, [[kurilno vrednost]] dizla (
