What are Joule and CHU

Definition of Joule

A joule is a derived unit of energy in the International System of Units (SI), named after the English physicist James Prescott Joule. It quantifies the amount of work done when a force of one newton acts over a distance of one meter. In practical terms, one joule can be defined as the energy transferred to an object when a one-ampere electric current passes through a one-ohm resistor for one second. It serves as a fundamental unit in physics, essential for understanding energy transformations in various scientific and engineering contexts.

Definition of CHU

The term CHU stands for Centigrade Heat Unit, a non-standard unit of energy formerly used in the field of thermodynamics. It represents the amount of heat necessary to raise the temperature of one pound of water by one degree Celsius at a specified temperature. Though largely replaced by the more universal joule in modern scientific contexts, the CHU was once a prevalent measure in industries involving heating and cooling processes. Despite its decline in use, understanding the CHU remains important for historical context and in specific industrial applications where older measurement systems are referenced.

Joule/second/square Meter (W/m²) CHU/hour/square Foot (BTU/h·ft²)
1 W/m² 0.3162 BTU/h·ft²
10 W/m² 3.162 BTU/h·ft²
20 W/m² 6.324 BTU/h·ft²
50 W/m² 15.81 BTU/h·ft²
100 W/m² 31.62 BTU/h·ft²
200 W/m² 63.24 BTU/h·ft²
500 W/m² 158.1 BTU/h·ft²
1000 W/m² 316.2 BTU/h·ft²
2000 W/m² 632.4 BTU/h·ft²
5000 W/m² 1581 BTU/h·ft²

Conversion of Joule to CHU

1 W/m² = 0.3162 BTU/h·ft²
1 BTU/h·ft² = 3.162 W/m²

Example 1:
convert 10 W/m² to BTU/h·ft²:
10 W/m² = 10 × 0.3162 BTU/h·ft² = 3.162 BTU/h·ft²

Example 2:
convert 50 W/m² to BTU/h·ft²:
50 W/m² = 50 × 0.3162 BTU/h·ft² = 15.81 BTU/h·ft²

History of Joule and CHU

The Joule/second/square Meter to CHU/hour/square Foot Converter has its roots in the historical necessity to bridge different energy measurement systems. Initially, industries relied on localized units like CHU, which were intuitive for specific applications. However, with globalization and technological advancements, the need for a universal conversion tool became evident. Over time, the converter evolved, incorporating precise algorithms to ensure accurate conversions between these units, thus facilitating international collaboration and standardization in energy measurement and management.
