An erg is the CGS unit of energy equal to 1×10⁻⁷ joule, used mainly for small-scale mechanical, thermal, or electromagnetic energy measurements.

Where is the calorie (IT) used?

The calorie (IT) is a historical energy unit once used in classical thermodynamics and steam-engine calculations, particularly for heat required to raise water temperature.

Why convert from erg to calorie (IT)?

Converting from erg to calorie (IT) helps interpret or translate small energy values from CGS units into a historical thermal energy context, useful for legacy scientific and engineering data.

Supports legacy energy units often found in historical and classical scientific literature.
Browser-based and easy to use with a straightforward interface.

Examples

10 erg equals 2.388458966275e-7 calorie (IT).
100,000 erg converts to 0.002388458966275 calorie (IT).

Common Use Cases

Translating small energy quantities from CGS units used in astrophysics or electromagnetism.
Interpreting or converting steam-engine thermodynamics data from historical literature.
Converting pre-SI engineering energy values to a unit used in classical thermodynamics.

Tips & Best Practices

Use this tool primarily for converting legacy data or historical energy units.
Verify unit selections carefully to ensure accurate conversions.
Be aware that the units involved represent very small or historical energy quantities.

Limitations

Erg is a very small energy unit and calorie (IT) is largely obsolete, limiting practical application.
Conversions may appear trivial in magnitude and are most useful for interpreting older datasets.
Potential rounding or unit system discrepancies may affect exact precision.
