About these measurements
Energy can be transferred through work, heating, or electrical processes.
The base reference used here is the joule. One petajoule is 1e+15 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.
