BTU is a measure energy, not of temperature. As a result, the question has no sensible answer.
BTU x 1,055.056 = joules
The answer: 17070 BTU The math: 3414 BTU = 1 KVA (KW) so 5 KVA = 17070 BTU
1 BTU = 1055 Joules
Depends on the temperature of the water. If it is 32 degree water and you want 32 degree ice then you need a -144 BTU loss to change state from liquid to solid. It takes 1 BTU to raise the temperature of 1 pound of water 1 degree (F). If the water is 82 degrees then you would need a -50 BTU loss (+) 144 BTU to change state. TOTAL WEIGHT OF WATER (X) 1 BTU (X) Degrees desired of change. If it is ICE to WATER then it is the TEMP of ICE (X) .5 BTU (X) NUMBER OF DEGREES INCREASED = TOTAL BTU needs. If you change state in the process you have to add 144 BTU for 32 degree ICE to 32 degree WATER and 970 BTU for 212 degree WATER to 212 degree STEAM but only when you change state.
Birtishthermal unit 12000 btu
1 watt is equal to 3.41 btu/h. multiply 1 by 1500 and we get 1500 watts. multiply 3.41 by 1500 and we get 5115btu/h. Therefore we can come to the conclusion that 1500 watts < 45000 btu. 45000btu/h is higher than over 10 times 1500 watts.simplified answer = 45000 btu is hilariously higher than 1500 watts.-Tychusfindlay919P.S. if you meant 4500 btu/h then 1500 watts is higher
About 6 hours
Does not computeKilowatts do not convert to BTU and vice versa. The watt is a unit of power, whereas the BTU is a unit of energy. Perhaps you meant BTU/hr. 1.5E5 BTU/hr = 43.96 kilowattsYou could do a direct conversion into Killowatt hours though one would assume.1.5E5 BTU = 43.96 KWh

7 percent of 45000 = 31507% of 45000= 7% * 45000= 0.07 * 45000= 3150
6.7% of 45000 = 6.7% * 45000 = 0.067 * 45000 = 3,015
19% of 45000 = 19% * 45000 = 0.19 * 45000 = 8,550
11252.5% of 45000= 2.5% * 45000= 0.025 * 45000= 1125
38% of 45000 = 38% * 45000 = 0.38 * 45000 = 17,100
15 percent of 45000 = 675015% of 45000= 0.15 *45000= 6750
there are several types of heat measurement. BTU (British thermal unit) calorie, temp.
