BTU per Hour to Kilocalories Conversion
Converting BTU per Hour (BTU/h) to Kilocalories (kcal) is a common energy and power conversion. 1 BTU/h equals 0.00007 kcal. For example, 100 BTU/h is equal to 0.007005 kcal.
Quick Mental Math: BTU per Hour to Kilocalories
For energy conversions, identify the unit scale difference in the prefix or definition.
Why is converting BTU per Hour to Kilocalories tricky?
Energy unit conversions involve non-linear factors across different measurement systems.
Quick Reference Values
1 BTU/h = 0.00007 kcal. 5 BTU/h = 0.00035 kcal. 10 BTU/h = 0.0007 kcal. 25 BTU/h = 0.001751 kcal. 50 BTU/h = 0.003502 kcal. 100 BTU/h = 0.007005 kcal.
What is BTU per Hour?
BTU per Hour (BTU/h) is a unit of energy and power. BTU per hour (BTU/h) quantifies power as the rate of energy transfer equal to one British Thermal Unit delivered in one hour. It converts to approximately 0.293071 watts. This unit is commonly used to rate heating and cooling system capacities and thermal power consumption [nist-sp-811]. The concept of BTU per hour stemmed from the BTU to express continuous heat flow rates in heating and ventilation during the 19th century. It was formalized to measure energy transfer rates in thermal engineering applications [nist-sp-811]. BTU/h is standard in HVAC industry specifications in the US, Canada, and the UK. It is used to indicate the heating or cooling capacity of furnaces, air conditioners, and boilers where SI units are uncommon or supplemented [nist-sp-811].
What is Kilocalories?
Kilocalories (kcal) is a unit of energy and power. A kilocalorie equals exactly 1,000 calories and represents the amount of energy needed to raise the temperature of 1 kilogram of water by 1 degree Celsius. It is widely used to quantify food energy and is equivalent to 4,184 joules [bipm-si-brochure]. The calorie was introduced in the early 19th century by Nicolas Clément as a unit of heat energy. The kilocalorie became standard in nutrition science by the early 20th century to express food energy content [bipm-si-brochure]. Kilocalories are used globally in nutrition labeling, especially in the US and Europe, to indicate energy content of foods. Scientific contexts often prefer joules, but kcal remains prevalent in dietetics [nist-sp-811].
Common Misspellings
People often search for this conversion using these alternate spellings: btu per hr, btu/hour, btu per hours, btu per h, btu per hr, kilo calories, kcalorie, kilo-calories. All of these refer to the BTU per Hour to Kilocalories conversion.
