Ergs are small.)ġ erg equals 10 joules, 1 BTU is 1055.06 Joules and 1 KW-h is 3.6 million Joules respectively.
For example, if you want to convert “36 ergs in foot-pounds'', then using the unit converter, you can easily find that 36 ergs equal 2.65522e-6 foot-pounds. Considering the fact that all of these special units of energy are still measuring energy, we can convert these from one unit to another. There are also special units for light energy, magnetic energy, sound energy, radiant energy and electric field energy. Similarly, a BTU is the amount of energy necessary to up the temperature of 1 pound of water by 1 o F (Fahrenheit). A calorie is defined as the amount of energy required to raise the temperature of 1 gram of water by 1 o C (Celsius). The energy produced within the object during conduction or convention, which is called Thermal (Heat) Energy, is measured in calories or BTUs (British Thermal units). On our residential/commercial electricity supply bill, the amount of electric energy consumed is measured in kilowatt-hours (KW-h). Special Dimensional Units For Different Forms of EnergyĮnergy comes in various forms and can thus be defined in special dimensional units for different forms of energy. There is also exercise equipment named Ergometer. A dyne-centimetre is described as an erg (a unit of energy which is equivalent to 10 joules). You see Joules most often on surge suppressors. A couple of these units have specified names. To measure energy, any combination of force and distance could be used. Based on what means of measurement you use, this could be dyne-centimetres, Newton-metres or foot-pounds. Work, on the other hand, is defined as a force operating through a distance so the fundamental dimensional units of energy are force x distance. Hence, putting the dimension of mass as M, acceleration as and the dimension of displacement as L, we obtain the dimension of energy as Įnergy is the ability to perform an activity. Or, E= Mass x Acceleration x Displacement
We can find out the dimension of energy from the following equation. Therefore, the Dimension of Density is given byĭimension of Density = M 1 / L -3 Now putting capital M and L in the above equation, the dimension formula of density isĭensity refers to the mass per unit Volume Volume is basically the length so the unit of volume is cubic meter which is denoted by capital L. However, here kg is the unit of mass and for dimension, we represent the mass by capital M and the same goes for volume. Putting this into the mathematical equation, we get Density = kg/m 3.
Thus, the unit of mass is kg and the unit of volume is cubic meter 3. Density typically means mass divisible by volume, i.e., mass/volume.
