BTU per Hour to Joules Conversion
Converting BTU per Hour (BTU/h) to Joules (J) is a common energy and power conversion. 1 BTU/h equals 0.293071 J. For example, 100 BTU/h is equal to 29.3071 J.
Quick Mental Math: BTU per Hour to Joules
For energy conversions, identify the unit scale difference in the prefix or definition.
Why is converting BTU per Hour to Joules tricky?
Energy unit conversions involve non-linear factors across different measurement systems.
Quick Reference Values
1 BTU/h = 0.293071 J. 5 BTU/h = 1.465355 J. 10 BTU/h = 2.93071 J. 25 BTU/h = 7.326775 J. 50 BTU/h = 14.65355 J. 100 BTU/h = 29.3071 J.
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 Joules?
Joules (J) is a unit of energy and power. The joule is the SI unit of energy defined as the work done when a force of one newton moves an object one meter in the direction of the force. It equals one kilogram meter squared per second squared (kg·m²/s²). This definition aligns with the International System of Units as standardized by the BIPM [bipm-si-brochure]. The joule is named after James Prescott Joule, a 19th-century physicist who studied energy conservation. It was officially adopted as a unit of energy by the CGPM in 1948 to unify energy measurement standards internationally [cgpm-resolutions]. Joules are used worldwide in physics, engineering, and electrical industries to quantify energy, work, and heat. Countries using the SI system, including those in Europe, Asia, and the Americas, rely on joules for scientific and industrial applications [nist-si-guide].
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, joule, joul, jouls, juls. All of these refer to the BTU per Hour to Joules conversion.
