# Joules to Thermochemical calories Converter

Enter a value in joules to get its equivalent in thermochemical calories. Use the inverse button to switch conversion direction.

## Input data

- **Joules** - type: number; default: 1; step: 0.01

## How it works

cal = J × 0.239005736138.

## Quick examples

- **1 J → 0.239006 cal** - Joules: 1
- **100 J → 23.900574 cal** - Joules: 100
- **500 J → 119.502868 cal** - Joules: 500

## Understanding your result

The result expresses the value entered in joules as thermochemical calories. This tool uses the thermochemical calorie (cal). Food labels usually mean kilocalories (kcal), which are 1,000 cal.
