What is Wh kg mean?
What is Wh kg mean?
Wh/kg
Energy density is the measure of how much energy a battery contains in proportion to its weight. This measurement is typically presented in Watt-hours per kilogram (Wh/kg). A watt-hour is a measure of electrical energy that is equivalent to the consumption of one watt for one hour.
What is the unit of weight energy density?
Energy density | |
---|---|
SI unit | J/m3 |
Other units | J/L, W⋅h/L |
In SI base units | m−1⋅kg⋅s−2 |
Derivations from other quantities | U = E/V |
What is the unit of specific energy?
joule per kilogram
The SI unit for specific energy is the joule per kilogram.
What is wh on battery?
Capacity – Watt-hour (Wh): Another way to measure the capacity of the battery is in Watt-hours (Wh). Wh is calculated by multiplying the number of Amps with the battery voltage. So these batteries have the same capacity, only one works on 12 volts and the other on 24 volts.
What does WH mean in electricity?
Watt-hour
When considering electricity issues, to understand a difference between Watt (W) and Watt-hour (Wh) is important. ● W=a unit of power, the rate at which energy is generated or consumed 1000W=1kW(kilowatt) ● Wh=a unit of energy, the total amount of energy generated or consumed 1000Wh=1kWh(kilowatt hour)
How calculate Wh kg battery?
Calculation formula The energy density of a battery can be simply calculated using this formula: Nominal Battery Voltage (V) x Rated Battery Capacity (Ah) / Battery Weight (kg) = Specific Energy or Energy Density (Wh / kg).
What is Wh kg and WH Litre for petrol?
Material | By Volume | By Mass |
---|---|---|
Gasoline | 9,700 Wh/l | 12,200 Wh/kg |
Butane | 7,800 Wh/l | 13,600 Wh/kg |
LNG (-160°C) | 7,216 Wh/l | 12,100 Wh/kg |
Propane | 6,600 Wh/l | 13,900 Wh/kg |
How do you find the WH of a battery?
Multiply the given volts by the battery capacity, shown as milliamps or mAh. Divide the sum by 1,000 to get the watt-hour rating.
What is the meaning of wh in electricity?
watt-hour (Wh): The watt-hour (symbolized Wh) is a unit of energy equivalent to one watt (1 W) of power expended for one hour (1 h) of time . The watt-hour is not a standard unit in any formal system, but it is commonly used in electrical applications.
What is a watt-hour (Wh)?
TechTarget Contributor The watt-hour (symbolized Wh) is a unit of energy equivalent to one watt (1 W) of power expended for one hour (1 h) of time. The watt-hour is not a standard unit in any formal system, but it is commonly used in electrical applications. An energy expenditure of 1 Wh represents 3600 joule s (3.600 x 10 3 J).
