That depends on you. If you want, you can say 1 watt should be 0 dB.
1.58 kilowatts are equal to 1580 watts.
5500 watts is equal to 5.5 kilowatts.
One horsepower is approximately equal to 745.7 watts.
57 watts is equal to 57 watts. The term "watts" is a unit of power measurement, so the value remains the same regardless of context. Therefore, if you have 57 watts, it is simply 57 watts.
2.5 kVA is equal to 2500 watts.
If you want to work in watts, convert 25dB to a scalling factor: 3dB = 2 x input 10dB = 10 x input 20dB = 100 x input ...25dB = 10 ^ (25/10) = 316.2 x input So the output is 15 Watts x 316.2 = 4.7kW If you want to work in dB, then convert 15 watts to dB: 10 * log |P| = dB = 10*log |15| = 11.76dB so the output is 11.76 + 25 = 36.76dB
1.58 kilowatts are equal to 1580 watts.
5500 watts is equal to 5.5 kilowatts.
1hp = 745.7 watts
A horsepower is equal to 746 watts, so 10 x 746 = 7,460 watts.
One horsepower is approximately equal to 745.7 watts.
The definition is that 746 watts equal one horse-power.
57 watts is equal to 57 watts. The term "watts" is a unit of power measurement, so the value remains the same regardless of context. Therefore, if you have 57 watts, it is simply 57 watts.
18650 watts
2.5 kVA is equal to 2500 watts.
10kW = 10,000 watts
1000MW is equal to 1GW
