Power is Energy in accordance to time: P = E/t . How to convert watts to joules How to convert electric power [ http://www.rapidtables.com/electric/electric_power.htm ] in watts (W) [ http://www.r... In order to convert Watts - a unit of power, to Joules - a unit of energy, we need to know a third variable - the time period of interest. The power P in watts (W) is equal to the energy E in joules (J) divided by the time period t in seconds (s): P(W) = E(J) / t(s) So. How to convert Watts to Joules. Formula is (Ah)*(V) = (Wh). How many watts are there in 2551 joules? The watts equation in mechanics is P = W/t, where W is work in joules and t is time in seconds. Therefore, 7 watts equal 7 joules per second, 12 watts equal 12 joules per second, 13,000 watts equal 13,000 joules per second, etc. The term MET, which was used in the national recommendations for exercise, is often used to estimate energy expenditure and work rate. You don’t - it is a unit of energy. You use them to quantify an amount of energy in the SI system. You can calcuate the SI quantity of energy by us... The power P in watts (W) is equal to the energy E in joules (J), divided by the time period t in seconds (s): Q: How do you convert 130 Joule (J) to Watt Hour (Wh)? You can calculate joules from watts and seconds, but you can't convert watts to joules since watt and joule units represent different quantities. Since Watt is just Joules per second, this is roughly equal to energy given off by a 100 Watt light bulb! If you multiply the number of watts by the number of seconds, you’ll end up with joules. How to convert kWh to joules. One kilowatt-hour is equal to 3600000 joules: 1kWh = 3600000J = 3.6⋅106J = 3.6MJ.
