Just like the odometer on your vehicle that shows the actual distance travelled by the vehicle, electricity meter shows the amount of electricity that is used. So a 100-Watt bulb if kept on for 10 hours will consume: 100 x 10 = 1000 Watt-Hour = 1 Kilowatt-Hour (kWH) = 1 units (on your meter).

## How many kilowatts are in a unit of electricity?

Units of electricity are measured in kilowatt hours (kWh’s). Therefore one unit of electricity is equal to one kilowatt hour (kWh) of electricity used.

## How is electric meter measured in units?

The most common unit of measurement on the electricity meter is the kilowatt hour [kWh], which is equal to the amount of energy used by a load of one kilowatt over a period of one hour, or 3,600,000 joules.

## How do you read meter units?

Dial meter

- Stand directly in front of your meter.
- Read the dial on the left first. (Ignore the dial underneath).
- Look at the two numbers the pointer is between and record the lowest number. (If the pointer is between 9 and 0, record 9.)
- Do the same with each dial, reading left to right.

## How does an electricity meter work?

Electricity meters function by measuring the instantaneous voltage and current to show how much energy has been used. Essentially, electric meters count how many kilowatts of electricity your house or flat consumes, and this is used to calculate your bill based on your provider’s unit cost in kilowatt-hours (kWh).

## What is meter reading in electricity?

Your annual electricity consumption is measured directly on the meter. This counts the number of kilowatt hours (one of the units used to measure energy) delivered to you. Each time your meter is read, the difference between the reading displayed by the meter and that of the previous year is calculated.

## What is the full form of kWh?

A kilowatt hour (kWh) is a measure of energy. So a 1,000 watt drill needs 1,000 watts (1 kW) of power to make it work, and uses 1 kWh of energy in an hour. That’s why, if you leave a TV or computer on standby, it is still using power and creating a kWh cost on your energy bill.

## Do smart meters work without wifi?

No. Smart meters use an entirely separate, bespoke wireless system. You don’t need Wi-Fi in your home for it to work and it won’t use your Wi-Fi if you have it. Your smart meter and in-home display communicate via a secure national network which is solely for smart meters.
