Hi All
I wanna know how much it cost to run electrical appliances, in my case it is air purifier.
Since I switch it on almost 24/7, i wanna know how much it cost to run per hour.
1) Air Purifier 1 - Label says power consumption is 10w
2) Air Purifier 2 - Label says power consumption is 90w
Assume TNB's lowest tariff rate i.e. RM0.218 per kWh
Anybody here can help? TIA
If you have something that consumes 1000W, then you will be using 1 kW every hour, for a price ofI wanna know how much it cost to run electrical appliances, in my case it is air purifier.

(1000/1000) * 0.218 = RM 0.218 every hour, or 21.8 sen per hour
If 2000 W consumption....
(2000/1000) * 0.218 = RM 0.436, or 43.6 sen per hour
If you have something that consumes 90W then you will be using
(90/1000) * 0.218 = RM 0.019 (less than 2 sen per hour at the 0.218 rate)
