# Thermochemical calories to Joules Converter

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

## Input data

- **Thermochemical calories** - type: number; default: 1; step: 0.01

## How it works

J = cal ÷ 0.239005736138.

## Quick examples

- **1 cal → 4.184 J** - Thermochemical calories: 1
- **100 cal → 418.4 J** - Thermochemical calories: 100
- **500 cal → 2,092 J** - Thermochemical calories: 500

## Understanding your result

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