The formula for calculating watt-hours is Watts x Hours Wh.

. Off Grid Solar Watt Hour Calculator. For example a 10 watt LED lightbulb that runs for 1 hour uses 10 watt hours 10 Wh of electricity. When you have the Wh you have to convert Wh to Ah.

The formula is W h Wh. Enter the Voltage and the Ampere-hours. Watt hours Wh Amp hours Ah Volts V Example Lets say you have a 12V battery with a 50Ah capacity.

If we want to calculate how much energy - so in other words how many watt-hours - are stored in a battery you need information about the electric charge in the battery. To convert W to Wh you need to multiply the number of Watts by the number of hours. Just visit Goal Zeros website for our calculator.

To calculate your batterys watt hours youd multiply 50Ah 12V. Enter the power in watts W time period in hours h then press the Calculate button to get the result in watt-hours Wh. The calculator will calculate the battery life if the Watt Hour and the battery voltage is known.

So if you have 100 watts running over four hours that equals 400 WHs 100400. You can calculate watt-hour from watts and hours but you cant convert watts to watt-hour since watts and watt-hour units represent different quantities. 100 amp hours Ah 12 volts V 1200 watt hours Wh In this example your car battery has a capacity of.

Category Calculators and Tools You may need to know the watt hour Wh rating of a lithium battery to determine how it should be shipped or to ensure you conform to. 1 BTU 02931 watt-hours 1 BTU 00002931 kWh 1 kWh 3412 BTU BTUh BTU per hour is a unit of power that represents the energy transfer rate of BTU per hour. Watts to Wh calculation Power in watts W Time period in hours.

The first step in figuring out how many solar panels you need and what size of off-grid solar power system will work for you is to know how much energy you. The Amp hour rating can be useful to know. 1 Wh 1 Ah 1 V Voltage V.

You can now calculate as 44Ah x 111 volts. As a point of reference the. Watt-hours milliamp-hours volts 1000 or Wh mAh V 1000 Wh to mAh.

The energy E in kilowatt-hours kWh is equal to the power P in watts W times the time period t in hours hr divided by 1000. Click Calculate and the result in Watt-hours will appear below. The energy E in kilowatt-hours kWh per day is equal to the power P in watts W times number of usage hours per day t divided by 1000 watts per.

To calculate your batterys watt hours youd multiply 100Ah 12V. 800Wh 12V 6667 Ah. Amp Hour to Watt Hour Conversion Calculator This calculator converts a battery or battery packs Watt hours Wh rating into its Amp Hours rating.

EkWh PW thr 1000 Watts to kWh calculation See also. Insert milliamp-hour mAh and voltage V and click on calculate to obtain Watt hours Wh or vice versa. If that same lightbulb runs for 2 hours it uses 20 watt hours 20 Wh of.

To do this you have to divide watt-hours by voltage 12V for batteries. Then fill in this box with the duration in hours and click on Calculate. Here is the formula Battery Life Watt Hours Voltage x Current in.

The battery will last 2 hours. An 111 volt 4400 mAh battery first divide the mAh rating by 1000 to get the Ah rating 44001000 44ah. Watts to watt-hour calculation.
