To convert from energy to electrical charge, use the formula below in conjunction with the voltage. Q (mAh) = E (Wh) × 1,000 V (V) Thus, the charge in milliamp-hours is equal to the watt-hours times 1,000, then divided by the voltage. You can also convert mAh to Wh using a similar formula. For example, let''s convert 10 Wh at 12 V to mAh. So ...

Consider using a computer monitor that is 75 watts continuously for 5 hours daily. To determine the total energy consumed by the monitor during this period, you can use the watts-to-watt-hours conversion: watt-hours = watts × hours. 75 W × 5 hrs = 375 Wh. Therefore, the computer monitor consumes 375 watt-hours of energy each day.
