1 calorie equals 0.001 kilocalorie.
The calorie and kilocalorie are units measuring energy. Since 1 kilocalorie equals 1000 calories, converting calories to kilocalories involves dividing the calorie value by 1000. Therefore, 1 calorie is equal to 0.001 kilocalorie.

Conversion Formula
The formula to convert calorie to kilocalorie is:
kilocalorie = calorie ÷ 1000
This formula works because 1 kilocalorie (kcal) equals 1000 calories (cal). So, to convert calories into kilocalories, the calorie value is divided by 1000. For example:
If you have 500 calories, converting to kilocalories means:
- 500 calories ÷ 1000 = 0.5 kilocalories
This simple division scales down the calorie amount to kilocalorie units.
Conversion Example
- Convert 250 calories to kilocalories:
– Take the calorie value: 250
– Divide by 1000:
250 ÷ 1000 = 0.25 kilocalories - Convert 1200 calories to kilocalories:
– Start with 1200 calories
– Divide by 1000:
1200 ÷ 1000 = 1.2 kilocalories - Convert 75 calories to kilocalories:
– Take 75 calories
– Divide by 1000:
75 ÷ 1000 = 0.075 kilocalories - Convert 5000 calories to kilocalories:
– Begin with 5000 calories
– Divide by 1000:
5000 ÷ 1000 = 5 kilocalories

Conversion Definitions
Calorie: A calorie is a unit measuring energy, mainly used in nutrition and scientific contexts. It quantifies the amount of heat required to raise the temperature of one gram of water by one degree Celsius. There are small calories and large calories, but this usually means the small calorie.
Kilocalorie: A kilocalorie equals 1000 calories and is a larger unit of energy commonly used to indicate the energy content in food. It represents the heat needed to raise the temperature of one kilogram of water by one degree Celsius and is sometimes called a “Calorie” with a capital C in dietary contexts.
Conversion FAQs
Why is 1 calorie equal to 0.001 kilocalorie?
Because 1 kilocalorie contains 1000 calories, the conversion between the two units involves dividing the calorie value by 1000. So 1 calorie divided by 1000 equals 0.001 kilocalorie. This unit relationship is fixed, so the conversion is always consistent.
Can calories be negative in energy conversions?
Negative calories can appear mathematically when values represent energy loss or deficit, but physically it is unusual. Negative energy values might indicate energy consumed rather than provided. The conversion process remains the same regardless of sign.
Is calorie the same as kilocalorie in food labeling?
No, food labels often use “Calorie” with a capital C to mean kilocalorie. Technically, a calorie is smaller (1/1000th of a kilocalorie), but in nutrition, 1 Calorie equals 1 kilocalorie. This can cause confusion between the terms.
What happens if I forget to divide by 1000 when converting?
If you don’t divide by 1000, the value remains in calories instead of kilocalories, causing results to be off by a factor of 1000. This mistake can lead you to overestimate energy amounts by a thousand times.
Is the conversion formula different for other energy units?
Yes, other units like joules or BTUs use different conversion factors. The calorie to kilocalorie formula is unique because it depends solely on the 1000 calorie per kilocalorie ratio, which does not apply to other energy units.
