What is the cgs and si unit of power

The CGS unit of power is erg per second.

We can define power as the rate of doing work, it is the work done in unit time. The SI unit of power is Watt (W) which is joules per second (J/s). Sometimes the power of motor vehicles and other machines is given in terms of Horsepower (hp), which is approximately equal to 745.7 watts.

To convert an SI formula to cgs: Change ε0 to 1/(4π×10−3c2) and µ0 to 4π×10−7. The “strange” factor 4π × 10−3c2 is just 4π × 10−7c2 in SI system. Change the physical quantities to the same divided by the value in the third column of the table.

The SI unit of G is N. m²/kg- and CGS unit is the dyne.

Power (P) is the rate at which energy is transferred or converted. Thus, power equals work divided by time (P = W / t). The SI unit of power is the watt (W), in honor of Scottish inventor James Watt (1736 – 1819).

A. G. S. (Centimeter-Gram-Second system) A metric system of measurement that uses the centimeter, gram and second for length, mass and time. The units of force and work are the “dyne” and “erg.” Contrast with MKS system.

Acceleration is C.G.S unit cm/s2. Acceleration is S.I unit m/s2. The ratio of C.G.S and S.I unit is. cm/m.

Power can be expressed in many different units, all of which can be expressed as a unit of energy divided by a unit of time. The most common unit is the watt (W), defined as 1 joule (J) of energy per second.
