Easily convert between kilojoules and Calories.

Input your kilojoules and see how many Calories this converts to.

You can also convert the other way from Calories to kilojoules.

Calorie counting is a widely adopted weight loss technique, and food labels often only show either Calories or kilojoules.

This is a simple app but performs its purpose in an efficient and accurate way.
