Large converted values can lead to very high numbers that are cumbersome without scientific notation
-
Erg's usage has declined in favor of joules in modern contexts, limiting common use
-
Conversion may be less practical outside specialized scientific or historical applications
Frequently Asked Questions
-
What is a kilocalorie (thermochemical)?
-
A kilocalorie (thermochemical), symbol kcal (th), is a unit of energy equal to 1,000 thermochemical calories and exactly 4,184 joules, often used to express food energy.
-
What is an erg unit used for?
-
An erg is a CGS unit of energy used mainly in astrophysics, classical mechanics, electromagnetism, and to interpret older scientific literature.
-
Why convert kilocalorie (th) to erg?
-
Converting kilocalorie (th) to erg helps translate common food or thermal energy measurements into a scientific CGS unit for specialized calculations and historical data.
