What is a thermochemical calorie (cal (th))?

It is an energy unit exactly equal to 4.184 joules, historically used in thermochemistry before the SI joule became standard.

Why convert calories (th) to gigatons?

To translate smaller or historical energy values into very large-scale units for comparison with events like asteroid impacts or nuclear explosions.

Is the gigaton unit precise for calculations?

No, the gigaton is mainly an approximate order-of-magnitude unit, so it is not intended for precise energy computations.

Tips & Best Practices

Always verify the context of your thermochemical calorie data before conversion.
Use the gigaton unit primarily for broad, order-of-magnitude energy comparisons.
Refer to the included examples as guides for scaling your values correctly.
Remember the thermochemical calorie is mostly of historical or educational use.
Avoid using the gigaton unit for detailed or precise energy calculations.

Limitations

Gigaton is a non-SI, approximate unit suitable mostly for rough estimates.
The thermochemical calorie is an outdated unit, so conversions apply mainly to historical data.
Converted values often result in extremely small fractions of gigatons, limiting direct practical use.
This conversion tool does not support detailed accuracy or rounding beyond basic multiplication.
