thermochemical kilocalorie to thermochemical calorie
Convert thermochemical kilocalorie (kcal) to thermochemical calorie (cal). Use an editable energy converter, conversion formula, and reference table.
1 kcal = 1,000 cal
Conversion formula
One thermochemical kilocalorie equals 1,000 thermochemical calorie. Multiply your value in thermochemical kilocalorie by this factor to get thermochemical calorie. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 thermochemical kilocalorie:5 × 1,000 = 5,000 cal

About these measurements
Energy can be transferred through work, heating, or electrical processes.
The base reference used here is the joule. One thermochemical kilocalorie is 4,184 base units; one thermochemical calorie is 4.184 base units.
Important distinctions
Calorie and BTU definitions vary. These pages label thermochemical calories and International Table BTUs explicitly.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
