TWh or terawatt/hour

My comment:

1 térawatt-heure (TWh) = 1 000 GWh = 1 000 000 MWh = 1 000 000 000 kWh = 1 000 000 000 000 Wh ; unit of energy often used in engineering texts. Hope this makes sense.

TWh is an international symbol, keep it as is. By the way it is not terawatt/hour, it is terawatt*hour

Thanks, Claude. I understand what it means, but abbreviations often escape me. It's been a while I haven't touched SI units in engineering. By the way, we need to think of pico-, femto-, nano-, etc. These do creep up quite often. I think the abbreviations are p, f, n.

Actually, it should be Twh in English; just a typographical error. 1 térawatt-heure (TWh) = 1 000 GWh = 1 000 000 MWh = 1 000 000 000 kWh = 1 000 000 000 000 Wh ; unit of energy often used in engineering texts. Hope this makes sense.
