You can calculate joules from watts and seconds, but you can't convert watts to joules since watt and joule units represent different quantities.Watts to joules calculation formulaThe energy E in joules (J) is equal to the power P in watts (W), times the time period t in seconds (s):...
You can calculate kilojoules from watts and seconds, but you can't convert watts to kilojoules since watt and kilojoule units represent different quantities. Watts to kJ calculation formula The energyEin kilojoules (kJ) is equal to the powerPin watts (W), times the time periodtin seconds (s)...
The watts to joules formula is: E(J)= P(W)× T(s) Thus, the energyEin joules is equal to the powerPin watts times the timeTin seconds. To calculate the joules of energy exerted, substitute the watts and time in seconds in the formula and solve. ...
384.6 yotta watt seconds = 4.717 million tons (mass/sec) = 283 million ton (mass/ min) = 16,981 million ton (mass/hour) = 407,554 million ton (mass/day) = 148.9 trillion ton (mass/year) times 4 billion years = 0.59 tera tera tons (mass/4 billion years) = 0.59 yotta tons (mas...

In mechanics, the definition of power is the rate of doing work W. It's defined as W/t, where t is the time it takes for the work to be completed. To get the result in watts, work must be expressed in joules, and time must be expressed in seconds....
Curious about the different types of electrical power? In this lesson, we'll define DC and AC power, provide a few examples, and provide a quiz to check your understanding. Related to this Question Explore our homework questions and answers library ...
PowerP= work / time(W⁄t).EnergyEis in joules, and timetis in seconds. 1 W = 1 J/s. Power = force multiplied by displacement divided by timeP = F×s / tor Power = force multiplied by speed (velocity)P = F×v. Undistorted powerful sound is not found in these formulas. Please...
e.g. joules = watts * seconds. kilowatt hour is watts times hours. kWh = W * hr.“if the machines produce 24/7/365” to “if the machines produce 24 hours/day * 7 days/week * 52 weeks/year or 365 days/year or 8760 hours/year (actually 365.26 days/year or 8766 hours/year) ...
So … one Watt/m2 applied for one year gives us 1 * 31.6E6 Joules/m2 per year. (Watts/m2 times seconds in 1 year.) To get total Joules for the planet, we need to multiply that answer by 5.1E14 square metres, to include the total surface area. So one Watt/m2 of forcing, acting...
