There are 3.966 BTU in a kilocalorie (kcal), and 1 kcal raises 1 kg of water 1 degree C, but to work through it:
1 BTU raises 1 pound of water 1 degree F, and 1 kg = 2.20 pounds, therefore:
2.20 BTU raises 1 kg of water 1 degree F, and 1 litre of water weighs 1 kg (basically), therefore:
2.20 BTU raises 1 litre of water 1 degree F, and a 1 degree change in F equals 5/9 degree C, therefore:
2.20 BTU raises 1 litre of water 5/9 degree C, therefore:
3.96 BTU raises 1 litre of water 1 degree C.
One BTU is the energy required to raise one pound of water by one degrees. Therefore, your answer would be one half.

That will completely depend on how much water there is.
It doesn't work that way. There is not a certain number of btus to raise air temperature. You would have to know how much air. A BTU is the British Thermal Unit. That is the amount of energy required to raise the temperature of one pound of water one degree F.
212 - 80 = 132 degrees temperature increase x 1 pound water = 132 BTU
One BTU is the energy required to raise one pound of water by one degrees. Therefore, your answer would be one half.
To raise 1 pound of ice from 32°F to water at 32°F it requires 144 BTUs. Since you have 50 pounds of ice, you would need 50 * 144 BTUs to raise the ice to water at 32°F. To further raise the water from 32°F to 160°F, you would need an additional amount of BTUs based on the specific heat capacity of water.
To calculate the BTUs required to raise the temperature of water, you can use the formula: BTUs = (pounds of water) x (temperature change in °F) x (1 BTU). For 15 pounds of water going from 100°F to 120°F, the calculation would be: BTUs = 15 pounds x 20°F x 1 BTU = 300 BTUs.
To raise the temperature of 1 pound of water by 1 degree Fahrenheit, it requires 1 BTU (British Thermal Unit). Therefore, to heat water by 10 degrees, it would require 10 BTUs per pound of water. This value may vary slightly depending on the specific heat capacity of the water.
BTUs, or British Thermal Units, measure the amount of heat energy required to raise the temperature of one pound of water by one degree Fahrenheit. The formula to calculate BTUs is: BTUs = weight of water (in pounds) x temperature change (in degrees Fahrenheit) x 1. Alternatively, the formula can be expressed as: BTUs = (Flow rate in gallons per minute x change in temperature in degrees Fahrenheit) / 500.
To calculate the BTUs required to raise the temperature of 15 pounds of water, you can use the formula: BTUs = Weight of water in pounds × Temperature change in degrees Fahrenheit × 1 BTU So, the calculation would be: BTUs = 15 lbs × (130°F - 100°F) × 1 BTU = 15 lbs × 30°F = 450 BTUs.

There are no BTUs in an office water-cooler. But you can calculate how many BTUs are removed by the cooler. One BTU or British Thermal Unit is the amount of heat energy required to raise the temperature of one pound of water one degree Fahrenheit. There for when you remove one BTU you are lowering one pound of water one degree Fahrenheit. So if you know how many pounds of water you have and the temperature of the water you start with and the temperature of the water comming out of the cooler you can calculate how many BTUs the cooling unit of the water cooler has removed. BTU=Temp1 - Temp 2 X LB water
One measure does not directly translate to another. A BTU is the amount of heat that it takes to raise the temp of one pound of water by one degree F. A burning match, and a burning fireplace may both be at 650 degrees, but the fireplace gives off more heat (more BTUs)
It doesn't work that way. There is not a certain number of btus to raise air temperature. You would have to know how much air. A BTU is the British Thermal Unit. That is the amount of energy required to raise the temperature of one pound of water one degree F.
