How much is the electricity bill for air-cond if it is ON for one hour?

If you know its calculation, you will find out that air-cond’s consumption per hour is not that “scary” but once you accumulated the usage, it is actually a big amount.

Calculation of air-cond’s usage:

1 HP (horse power) = 746W(Watt) or 0.746KW(Kilo-watt)
1 KWH (Kilo-Watt-hour) = RM0.286
0.746 KWH = RM0.21 = 21 sen per hour

If you ON 8 hours per day (night) = RM0.21 x 8 hours = RM1.71
Usage for one month = RM1.71 x 31 days = RM52.90
This is the monthly usage for 1 HP air-cond.

Summary on air-cond’s consumption in RM:

1.0 HP = RM0.21 per hour = RM52.90 per month (one day 8 hours)
1.5 HP = RM0.32 per hour = RM79 per month (one day 8 hours)
2.0 HP = RM0.42 per hour = RM105 per month (one day 8 hours)
2.5 HP = RM0.53 per hour = RM130 per month (one day 8 hours)
