Which measurement would you typically use to express the weight of a refrigerant?

The most appropriate measurement to express the weight of a refrigerant is typically kilograms. Refrigerants are substances that exist in various states and can be heavy, so using a metric weight measurement like kilograms provides a more standardized understanding than smaller units like ounces. Kilograms are commonly used in many countries and industries globally, making it easier to compare and evaluate quantities, especially considering that refrigerants are often stored and used in larger volumes as part of HVAC systems.

While ounces can be used for lighter refrigerants or in very small applications, they are less common in the context of refrigerants. Gallons and liters measure volume rather than weight, which is not suitable for expressing the weight of a refrigerant directly. Therefore, kilograms stands out as the most universally accepted and practical unit for this purpose.
