1400 kilojoules (kJ) is approximately 334.43 American calories.
This conversion is done by converting the energy value in kilojoules to the American calorie unit, which differs slightly from the international calorie. Knowing this helps when comparing energy content on food labels or scientific measurements in the US.

Conversion Formula
The formula for converting kilojoules (kJ) to American calories is:
American calories = kilojoules × 0.2388458966275
This works because 1 kilojoule equals approximately 0.2388459 American calories. The American calorie is slightly different from the International calorie, making this factor needed when converting.
For example, converting 1400 kJ:
- Start with 1400 kJ
- Multiply by 0.2388458966275
- 1400 × 0.2388459 ≈ 334.3841 American calories
- Rounded to 4 decimals: 334.3841 cal
Conversion Example
- Convert 1000 kJ to American calories:
- Multiply 1000 by 0.2388459
- 1000 × 0.2388459 = 238.8459 American calories
- Convert 500 kJ to American calories:
- 500 × 0.2388459 = 119.4229 American calories
- Convert 2000 kJ to American calories:
- 2000 × 0.2388459 = 477.6918 American calories
- Convert 1234 kJ to American calories:
- 1234 × 0.2388459 ≈ 294.8763 American calories

Conversion Definitions
kJ (kilojoule): A kilojoule is a unit of energy in the International System of Units. One kilojoule equals 1000 joules. It measures energy, commonly used in food energy labeling, physics, and engineering to quantify work or heat.
American (calorie): The American calorie is a unit of energy used in the United States, slightly different from the International calorie. It equals about 4.184 joules, and is often used in nutrition to represent energy content in foods.
Conversion FAQs
Why does the conversion factor between kJ and American calories differ from international calories?
The American calorie is defined differently from the international calorie, which causes a slight variation in the conversion factor. While both measure energy, the American calorie is based on an older standard, making it about 0.238846 times a kilojoule, rather than exactly 0.239.
Can I just multiply by 0.24 to get American calories from kJ?
Multiplying by 0.24 gives an approximate result, but it introduces small errors. For precise conversions, using 0.2388459 is better. If rough estimation is acceptable, 0.24 is easier but less accurate.
Is converting 1400 kJ to American calories necessary for food labels in the US?
Yes, in the US food industry, energy is often expressed in American calories, so converting kJ values helps consumers understand energy intake. Although many labels now use kilocalories, some scientific contexts still require American calorie conversions.
Does temperature or pressure affect kJ to American calorie conversion?
No, both kilojoule and American calorie are units of energy and not dependent on temperature or pressure. The conversion factor remains constant regardless of environmental conditions.
Why does the tool round to four decimal places?
Rounding to four decimals balances precision and readability. More decimals may not be meaningful for practical purposes, and fewer decimals could reduce accuracy in scientific or nutritional calculations.
