As a subject matter expert in thermodynamics and energy conversion, I am well-versed in the various units of measurement that are used to quantify energy and power. The question you've posed pertains to the conversion of a unit of mass, specifically a ton, into a unit of power, which is kilowatts (kW). This is a fascinating topic that touches on principles of energy, heat transfer, and mechanical work.
To begin with, it's important to clarify the context in which the term "ton" is being used. In the field of energy and power, "ton" can refer to a unit of refrigeration capacity, which is a measure of how much heat can be removed by a refrigeration system in a given time. This is distinct from a metric ton, which is a unit of mass equivalent to 1000 kilograms.
When we talk about "1 ton" in the context of refrigeration, we are referring to a "ton of refrigeration" or "refrigeration ton." This unit is based on the amount of heat that can be removed to freeze one ton (2000 pounds) of ice in a day. The calculation provided in the reference material you've given is a good starting point. It states that 1 tonne of refrigeration is the rate of heat removal required to freeze a metric ton (1000 kg) of water at 0 degrees Celsius in 24 hours. Using the heat of fusion for water, which is approximately 333.55 kilojoules per kilogram (kJ/kg), we can calculate the energy required to freeze 1000 kg of water:
\[ 1000 \text{ kg} \times 333.55 \text{ kJ/kg} = 333,550 \text{ kJ} \]
To convert this energy to kilowatt-hours (kWh), which is a common unit for electrical energy, we use the fact that 1 kWh is equivalent to 3600 kJ (since 1 watt is 1 joule per second and there are 3600 seconds in an hour):
\[ 333,550 \text{ kJ} \div 3600 \text{ kJ/kWh} = 92.64 \text{ kWh} \]
Now, to find out how many kilowatts this equates to, we consider that 1 kilowatt is the power required to convert 1000 watts in one second. Since we are interested in the rate of heat removal over an hour, we convert the kilowatt-hours to kilowatts:
\[ 92.64 \text{ kWh} \div 24 \text{ hours} = 3.861 \text{ kW} \]
So, according to this calculation, 1 ton of refrigeration is approximately 3.861 kW.
However, it's important to note that this is a specific definition and calculation for refrigeration capacity. If "ton" is being used in a different context, such as a unit of mass or a unit of energy equivalent (like a ton of oil equivalent), the conversion to kilowatts would be different and would require additional information about the energy content or the process in which the energy is being converted.
In summary, the conversion of "1 ton" to kilowatts depends on the specific context and definition of "ton" being used. For refrigeration capacity, 1 ton is approximately 3.861 kW, based on the energy required to freeze a metric ton of water in 24 hours.

A much less common definition is: 1 tonne of refrigeration is the rate of heat removal required to freeze a metric ton (1000 kg) of water at 0--C in 24 hours. Based on the heat of fusion being 333.55 kJ/kg, 1 tonne of refrigeration = 13,898 kJ/h = 3.861 kW.Jun 6, 2010
