Ventilation unit
Material for a ventilation unit (groupe de ventilation):
"ECONOMIQUE
Faible consommation électrique : 33 W-Th-C."
"Alimentation électrique 230 V – 1Ph – 50Hz
Intensité absorbée Petite vitesse 0.26 A
Intensité absorbée Grande vitesse 0.37 A
Puissance W-Th-C 33 W-Th-C"
Very simple question: do we use the same units in English?
Thanks.

W-Th-C
Yes
Thouh I'm not entirely sure just which meaning of 'Th' applies here, but I'm pretty sure it is an international standard unit just like the others.

standard : 35W-Th-C*.
micro-watt : 15W-Th-C*.
* Consommation moyenne calculée selon les règles th-C de la RT 2005.
So it's 'watts as calculated according to the th-C rules'

So it is clearly a specifically FR concept and process, probably necessary to keep it in FR and add an explanatory note somewhere — but it could get quite lengthy!

The only thing we can be pretty sure of is that W is indeed watt!

"W-Th-C consumption" would probably be your best bet — meaning 'power consumption calculated according to the W-Th-C method'
I would avoid using the unit 'watt' as a synonym for 'power consumption' — although it is is used this way a lot in lay language ("What wattage is your electric kettle?"), it always stands out rather unidiomatically in a more formal technical text.

Note from asker:
| "Watts as calculated according to the th-C rules", or wattage as...? |

: Seen this before bt can find no trace of it in EN originals. I think W is for watt, Th for thermal and C for consommation :http://www.atlantic.fr/nos-services/questions-reponses-avant...

Looks like it's even more complicated than either of us imagined, Nikki!

: All good points, Nikki. I think it's safest to keep close to the FR term and then explain.

Discussion
I know the units standardised by IEC and ISO, but I have never seen a "th".
I suspect that the "h" is an index to "t" and that "T" should be lower case.
