## What is the formula for 1 Joule?

Work (Joule)= F × D = [M1 L1 T-2] × [L1] = [M1 L2 T-2]. Therefore, Joule is dimensionally represented as [M1 L2 T-2].

## What is meant by 1 Joule work?

Joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. ... In electrical terms, the joule equals one watt-second—i.e., the energy released in one second by a current of one ampere through a resistance of one ohm.

## What is kJ per kg?

A kilojoule per kilogram (kJ/kg) is a decimal multiple of the SI-derived unit of specific energy, heating value, energy content, or heat of combustion per unit mass joule per kilogram. The joule per kilogram is equal to the useful energy released from one kilogram of fuel mass during its complete combustion.

## What is kJ H?

Kilojoule per hour (kJ/h) is the SI multiple of the derived power measurement unit joule per second (J/sec) or watt (W).

## How do you convert kWh to kW?

So, the power in kilowatts is equal to the energy in kilowatt-hours divided by the time-period measured in hours. For example, let's convert 48 kWh of energy consumption over a 24-hour time period to kW.

## How many kWh is a unit?

100 x 10 = 1000 Watt-Hour = 1 Kilowatt-Hour (kWH) = 1 units (on your meter).

## How is a kWh calculated?

A kilowatt-hour, expressed as kWh or kW·h, is a measure of energy that is equivalent to 1,000 watts of power for a 1-hour time period. ... To convert the power in watts to kilowatt-hours, multiply 100 watts by 1 hour, then divide by 1,000 to find the energy usage in kWh.

## How many kilowatts are in an hour?

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.

## Is 1 kW a lot?

One kilowatt is equal to 1,000 watts. Your electricity company charges by how much electricity you use per kilowatt hour (kWh). ... For example: A 100 watt light bulb uses 0.
