Energy Consumption Calculator Online



The formula for calculating Energy Consumption is

Energy Consumption E(kWh/day) =
P(W) × t(h/day) / 1000


Example of Calculations for current type DC:

Appliance : Air Conditioner

Power consumption (watts): 600

Hours of use per day : 1 h/day

Energy Consumption E(kWh/day) =
600 × 1 / 1000
= 0.6 kWh/day

Energy Consumption E(kWh/month) = 30 ×
600 × 1 / 1000
= 18 kWh/month

Energy Consumption E(kWh/year) = 365 ×
600 × 1 / 1000
= 219 kWh/year
