Kilojoules to Calories Converter
European food labels list energy in kilojoules, but most dieters think in calories — converting kJ to calories is the daily math of international nutrition. A 1,000 kJ meal is 239 food calories (kilocalories); a 500 kJ snack is about 120. One kilojoule equals 239.006 small calories — multiply kilojoules by 239.006, then divide by 1,000 for food calories. The converter above works instantly both ways, the table covers typical meals and snacks, and the FAQs untangle calories versus kilocalories once and for all.
