Every time you use an electrical appliance, you're consuming power. Since there's a cost to consuming this power, meters record the exact amount of electricity (kilowatthours) that flows into a building. Hydro-Québec's power system stops at the electricity meter in your home.
To calculate your consumption, Hydro-Québec subtracts your previous meter reading from your current reading.
The difference is multiplied by a figure that is shown on the meter, usually 10 (MULT 10).
If the needle is between two numbers, take the smaller number. If it points between 9 and 0, take the 9.
|The reading for the current period is:||7,523|
|The reading for the previous period was:||-||7,300|
|The difference between the two is:||=||223|
|This difference, multiplied by 10, gives:||2,230|
2,230 is the number of kilowatthours that will be billed.
