Costly rule
(lemm.ee)
Be sure to follow the rule before you head out.
Rule: You must post before you leave.
What you're describing is kWh, not kW/h. You need to multiply power with time to get back to energy. An appliance using 1kW of power for 1h "uses" 1kWh of energy. The same appliance running for 2h requires 2kWh instead.
kW/h doesn't really make sense as a unit, although it could technically describe the rate at which energy consumption changes over time.
Autocorrect seems to disagree, but autocorrect doesn't know shit about power vs energy. Fixed it.
