How do you find the joules?
In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph.
How do you calculate joules in chemistry?
Then, in terms of SI base units a joule is equal to a kilogram times meter squared divided by a second squared (kg×m2s2) ( kg × m 2 s 2 ) . Another common unit of energy that is often used is the calorie (cal), which is equivalent to 4.184 J.
What is the formula of 1 Joule?
Joule is the SI unit of work done. Therefore, the dimensional formula of Joule is the same as that of the work done. On substituting equation (2) and (3) in equation (1) we get, Work (Joule)= F × D = [M1 L1 T-2] × [L1] = [M1 L2 T-2].

How do you calculate kW to kWh?
- Divide the wattage by 1,000 to calculate kW: 1500 watts 1,000 = 1.5 kW.
- Multiply the kilowatts by the hours of daily use: 1.5 kW X 2 hours = 3 kWh per day.
- Find the total energy usage for a month (30 days): 3 kWh X 30 days = 90 kWh per month.

What is J in Chem?
J (J): (1) The joule. An International System of Units energy unit equal to an applied force of one newton through a distance of one meter, or the energy equivalent to passing an electric current of one ampere through a resistance of one ohm for one second.
How do you convert joules to kilojoules?
To convert a joule measurement to a kilojoule measurement, divide the energy by the conversion ratio. The energy in kilojoules is equal to the joules divided by 1,000.
How do you calculate mass to joules?
Albert Einstein proposed that mass and energy are related by the equation “E = m_c^2,” where “E” is the object’s energy in joules, “m” is the object’s mass and “c” is the speed of light. This equation, called the mass-energy equivalence formula, is used to convert between energy and mass.
What is energy formula?
The energy stored in an object due to its position and height is known as potential energy and is given by the formula: P.E. = mgh. Unit. The SI unit of energy is Joules (J).
What is the energy equivalent of 3 kg of mass?
If we choose mass in kilograms and the speed of light in meters per second, then the answer will be in Joules. The mass (from the above example) would be 3 kilograms and the speed of light (c) is 299,792,458 meter per second. 9 x 1016 mtr²/sec². which equals 2.7 x 1017Joules.
What is the weight of 1kg mass object on the Earth?
In other words, an object with a mass of 1.0 kilogram weighs approximately 9.81 newtons on the surface of the Earth, which is its mass multiplied by the gravitational field strength.
