Calories to Tons of Refrigeration Conversion
Converting Calories (cal) to Tons of Refrigeration (TR) is a common energy and power conversion. 1 cal equals 0.00119 TR. For example, 100 cal is equal to 0.11897 TR.
Quick Mental Math: Calories to Tons of Refrigeration
If 10 calories is released in 1 second, it is about 0.0119 tons of refrigeration.
Why is converting Calories to Tons of Refrigeration tricky?
calories to tons of refrigeration mixes energy with power, so the missing time step is the trap: the same energy gives different power over 1 second and 1 hour.
Quick Reference Values
1 cal = 0.00119 TR. 5 cal = 0.005948 TR. 10 cal = 0.011897 TR. 25 cal = 0.029742 TR. 50 cal = 0.059485 TR. 100 cal = 0.11897 TR.
What is Calories?
Calories (cal) is a unit of energy and power. The calorie (cal) is defined as exactly 4.184 joules. It quantifies the energy needed to raise the temperature of one gram of water by 1°C under standard conditions. The calorie is widely used in chemistry and nutrition to express energy content [bipm-si-brochure]. The calorie was introduced in the early 19th century by Nicolas Clément and standardized internationally in the 20th century. It was adopted for practical energy measurement in chemistry and food science before the joule became the SI unit [bipm-si-brochure]. Calories remain common in food labeling, nutrition, and chemistry worldwide. The dietary Calorie (kcal) is prevalent in the US, Europe, and many countries while scientific contexts prefer the joule [bipm-si-brochure].
What is Tons of Refrigeration?
Tons of Refrigeration (TR) is a unit of energy and power. A ton of refrigeration is a unit of power used to describe the heat-extraction capacity of refrigeration and air conditioning systems. One ton of refrigeration equals 12,000 BTU per hour or approximately 3.517 kilowatts (kW). This unit quantifies the rate at which heat is removed to produce cooling [nist-si-guide]. The ton of refrigeration originated in the early 20th century, based on the cooling effect of melting one ton of ice over 24 hours. It was formalized to standardize refrigeration system capacities during industrial refrigeration advancements [nist-si-guide]. Tons of refrigeration are used globally in HVAC industries, especially in North America and parts of Asia, to rate cooling equipment. International standards bodies recognize it, though SI units like watts are preferred in scientific contexts [nist-si-guide].
Common Misspellings
People often search for this conversion using these alternate spellings: calorie, cal, calory, calo, ton of refrigeration, tons refrigeration, ton refrigeration. All of these refer to the Calories to Tons of Refrigeration conversion.
