Power per watt
There is no unit conversion relationship between the two, because watt is the power unit of the international system of units, and Ma is the measurement unit of current
watt is defined as 1 joule per second (1J / s), which is the rate of energy converted, used or dissipated (measured in joules) per second. In the system of electrical units, it is volt times ampere times power factor (1V · a, 1 volt ampere for short)
The size ofpoint current is called current intensity, which refers to the amount of charge passing through a certain section of the wire in unit time. The expression i = q / T, and the amount of charge passing through a Coulomb per second is called "ampere". Ampere is a basic unit in the international system of units
extended data:
common conversion relationship between watt and Ma:
1a (a) = 1000mA (MA)
1mA (MA) = 1000 μ A (microampere)
1mA = 10 ^ - 3 A (a), i.e. 1mA = 0.001a
1A = 10 ^ (3) MA = 10 ^ (6) μ A = 10 ^ (9) Na, i.e. 1A = 1000mA = 1000000 μ A = 1000000000na
1kW = 1000W; 1 MW = 1000 kW
performance / watt, energy consumption ratio, performance to power consumption ratio. The higher the value is, the better the hardware or other electrical performance is, and the higher the efficiency is (recing thermal power consumption)
as for the indicators, in terms of hardware, every new architecture or new process may increase the energy consumption ratio, so I think there should be no hard indicators in terms of hardware - P4 Prescott is more than 100 watts, and the current common al core power consumption is less than 80W, and the energy consumption ratio is several times higher
high energy consumption ratio is also advocated on household appliances, and energy efficiency labels are available on small household appliances.
Only power can't calculate current
The calculation formula ofElectric Power: P = w / T = UI
In the pure resistance circuit, according to Ohm's law, u = IR can be substituted into P = UI to get P = I2R = (U2) / Rin dynamics: power calculation formula: 1. P = w / T (average power) 2. P = FV; P=Fvcos α Instantaneous power)
P in the formula represents power, unit is "watt", abbreviated as "watt", symbol is w
W indicates work. The unit is Joule and the symbol is J
t means time, the unit is "second", and the symbol is & quot; s"

< H2 > extended data meaning of power:
power is the physical quantity that represents the speed of work done by an object. In physics, power P = work J / time t, and the unit is watt. We often see power units in the media, such as kW, PS, HP, BHP, whpmw, etc., as well as CV previously used in Italy. Here, side kilowatt kW is the international standard unit, 1kW = 1000W, If 1000 joules of work is done in one second, the power is 1kW
in the automotive field, the largest power machine is the engine. The power of the engine is calculated by the torque, and the calculation formula is quite simple: power (W) = 2 π× Torque (nm) × Speed (RPM) / 60, after simplified calculation: power (W) = torque (nm) × Speed (RPM) / 9.549
friends, please adopt the correct answer in time, and may help you next time. If you adopt the correct answer, you can also get the wealth value, thank you.
Joule is the unit of energy; Watt is the unit of power, the ratio of work to the time it takes to complete it. The two cannot be converted. Joule can be converted to watt hour or kilowatt hour. The unit of energy released by a fully charged capacitor is Joule
watt is the unit of power in the international system of units. Watt is defined as 1 joule per second (1J / s), the rate of energy converted, used or dissipated (measured in joules) per second. In the system of electrical units, it is volt times ampere times power factor (1V · a, 1 volt ampere for short)
Joule is the metric unit of heat. It is founded in memory of James Prescott Joule, a famous British physicist The conversion relationship between Joule and watt hour or kilowatt hour is as follows: 1 watt hour (w · h) = 1W × 3600s = 3600j
1 kwh / degree (kW · h) = 1000W × 3600s = 3600000j
watt is the unit of power, which refers to the ratio of work to the time taken to complete this part of work. The formula is p = w / T. Power is a physical quantity that describes how fast work is done. According to the power and working time, the work can be calculated: w = Pt

Joule calorie:
1 kilojoule (kcal) = 4.184 kilojoule (kJ)
1 kilojoule (kJ) = 0.239 kilojoule (kcal)
1 card = 4.184 Joule
1 joule = 0.239 card
Joule watt:
1 joule (J) = 1 watt × Second (w · s)
