1 joule equals approximately 9.8692×10-24 to.
This conversion is based on the relation that 1 to (tonne of TNT) equals exactly 4.184×109 joules, therefore 1 joule is a very small fraction of a to. The joule is a unit of energy in the SI system, while to represents an energy unit derived from the explosive power of one tonne of TNT.

Conversion Formula
The formula to convert joule to to uses the fixed energy equivalence where 1 tonne of TNT (to) equals 4.184×109 joules. To convert joule to to, divide the joule value by 4.184 billion (4,184,000,000).
This works because the to unit quantifies energy released by an explosive mass of TNT, standardized at exactly 4.184 gigajoules. So, the joule value represents a portion of that energy.
Example:
- Given 1 joule, calculate to: 1 ÷ 4,184,000,000 = 2.39×10-10 to
- Given 10 joules: 10 ÷ 4,184,000,000 = 2.39×10-9 to
Conversion Example
- Convert 5000 joules to to:
- Divide 5000 by 4,184,000,000,
- 5000 ÷ 4,184,000,000 = 1.195×10-6 to,
- So, 5000 joules equals approximately 0.000001195 to.
- Convert 2,000,000 joules:
- Divide 2,000,000 by 4,184,000,000,
- 2,000,000 ÷ 4,184,000,000 ≈ 0.000478 to,
- Meaning 2 million joules is nearly 0.000478 to.
- Convert 0.1 joules:
- 0.1 ÷ 4,184,000,000 ≈ 2.39×10-11 to,
- Very small fraction of one to.

Conversion Definitions
Joule: A joule is the SI unit of energy, defined as the work done when a force of one newton displaces an object by one meter in the direction of the force. It quantifies energy, work, or heat, used across physics and engineering contexts as a standard energy measurement.
To: The ‘to’ unit represents one tonne of TNT equivalent energy, standardized as exactly 4.184 gigajoules. It’s commonly used for measuring large explosive or energy releases, such as nuclear blasts or industrial explosions, reflecting TNT’s energy yield.
Conversion FAQs
Why is the to unit based on TNT energy?
The to unit is grounded on TNT energy because TNT was historically a standard explosive, with a consistent and measurable energy release. Using TNT equivalence allows comparing different energy events on a common scale, especially in explosive and military contexts.
Can I convert to back to joule easily?
Yes, to convert from to to joule, multiply the to value by 4,184,000,000. This reverses the division used in the joule to to conversion, restoring the energy amount in joules accurately.
Is the joule to to conversion linear for all values?
Yes, the conversion is linear because both units measure energy, just different scales. Multiplying or dividing by the constant 4.184×109 keeps the proportional relationship intact for any value.
Are there any practical applications for converting small joule values to to?
Small joule values converted to to result in very tiny fractions, rarely used in practical explosive measurements. However, it might be relevant in precise scientific modeling or simulations involving energy scales crossing from microscopic to macroscopic.
What causes negative joule values in the conversion chart?
Negative joule values represent energy removal or opposite direction work. When converting those to to, the negative sign remains, indicating energy loss or reverse effect relative to the TNT equivalent scale.
