What Is This Tool?
This converter transforms energy values from the thermochemical calorie (cal (th)), a historical unit of energy, into tons (explosives), a unit commonly used to quantify energy release from detonations like TNT explosions.
How to Use This Tool?
-
Enter the amount of energy in calorie (th) you wish to convert.
-
Select the source unit as calorie (th) and the target unit as ton (explosives).

Key Features
-
Converts energy from calorie (th), defined exactly as 4.184 joules, to ton (explosives), equal to approximately 4.184 × 10⁹ joules.
-
Supports understanding energy magnitudes relevant to explosions, mining, and impact events.
-
Easy-to-use interface for quick energy unit conversions between historical and large-scale explosive units.
-
Provides exact conversion rate and example values to guide users.
-
Browser-based tool requiring no installation.
Examples
-
Converting 5,000,000,000 cal (th) results in 5 ton (explosives).
-
Converting 200,000,000 cal (th) gives 0.2 ton (explosives).
Common Use Cases
-
Relating heat values from older calorimetry data to explosive energy scales.
-
Estimating explosive yield for military, mining, or scientific purposes.
-
Comparing historic thermochemical results with modern explosive energy units.
-
Analyzing energy release in planetary impact events or industrial explosions.
Tips & Best Practices
-
Use the tool when working with historical thermochemical energy data.
-
Refer to the exact conversion factor of 1 cal (th) = 1 × 10⁻⁹ ton (explosives).
-
Understand that ton (explosives) is approximate and depends on TNT equivalence conditions.
-
Cross-check results when comparing to modern joule-based data for accuracy.
Limitations
-
Ton (explosives) is an approximate measure due to varying TNT equivalence by explosive type.
-
Calorie (th) is a historical unit replaced by joules, so conversions may involve approximations.
-
Conversion may not reflect precise energy for all explosive compositions or conditions.
Frequently Asked Questions
-
What is a calorie (th) in energy terms?
-
The thermochemical calorie (cal (th)) is a historical energy unit defined exactly as 4.184 joules, used in older thermochemical data.
-
What does a ton (explosives) represent?
-
A ton (explosives) is the approximate energy released by detonating one metric ton of TNT, standardized as about 4.184 × 10⁹ joules.
-
Why is the ton (explosives) unit approximate?
-
Because the TNT equivalence varies depending on explosive type and conditions, the ton (explosives) is an approximate energy measurement.
-
Can this converter be used for modern energy measurements?
-
The converter is best for relating historical calorie (th) data to explosive energy units; modern practice uses joules instead of calories.
Key Terminology
-
Calorie (th) [cal (th)]
-
A historical energy unit exactly defined as 4.184 joules, used in thermochemical contexts before joules became standard.
-
Ton (explosives)
-
A non-SI energy unit representing the approximate energy from detonating one metric ton of TNT, standardized at about 4.184 × 10⁹ joules.
-
TNT Equivalence
-
A measure comparing energy released by various explosives to that of TNT, affecting the accuracy of ton (explosives) units.
