Kilojoules And Calories On Your Devices
Phones, watches and tracking apps usually pick an energy unit based on your region, so many people in Australia and New Zealand see kilojoules while their diet plan is in Calories, or the other way round. These guides show exactly where the setting lives in the most popular apps and devices, and what happens to your goals and history when you switch.
Whichever unit you choose, the energy is the same: 1 Calorie = 1 kcal = 4.184 kJ. The best choice is usually the unit printed on the food labels you read most often, so your app and your groceries speak the same language.
