Joules to Ergs Conversion
Converting Joules (J) to Ergs (erg) is a common energy and power conversion. 1 J equals 10,000,000 erg. For example, 100 J is equal to 1,000,000,000 erg.
Quick Mental Math: Joules to Ergs
Multiply joules by 10.000.000 to convert to ergs.
Why is converting Joules to Ergs tricky?
joules to ergs uses multiple definitions of the same unit name.
Quick Reference Values
1 J = 10,000,000 erg. 5 J = 50,000,000 erg. 10 J = 100,000,000 erg. 25 J = 250,000,000 erg. 50 J = 500,000,000 erg. 100 J = 1,000,000,000 erg.
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].
What is Ergs?
Ergs (erg) is a unit of energy and power. An erg is a unit of energy equal to 10⁻⁷ joules in the centimeter-gram-second (CGS) system. It quantifies work or energy on a small scale, commonly used in physics before SI units became widespread. The erg relates to mechanical, thermal, and electromagnetic energy in CGS-based calculations [nist-si-guide]. The erg was introduced in the late 19th century within the CGS system to measure energy and work at microscopic scales. It was formalized as part of the CGS units by scientists including Wilhelm Ostwald to complement centimeter and gram units. The erg became less common after SI units like the joule were internationally adopted [nist-si-guide]. Ergs remain in use mainly in astrophysics, plasma physics, and historical scientific literature, especially where CGS units persist. They are uncommon in industry or engineering, replaced almost entirely by joules globally. Scientific bodies such as NIST recognize the erg but recommend SI units for new work [nist-si-guide].
Common Misspellings
People often search for this conversion using these alternate spellings: joule, joul, jouls, juls, ergs, erg, erggs, erges, erhg. All of these refer to the Joules to Ergs conversion.
