Enter the total energy (kJ) and the total time (days) into the Calculator. The calculator will evaluate the Kilojoules Per Day.

## Kilojoules Per Day Formula

KJD = E / T

Variables:

- KJD is the Kilojoules Per Day (kJ/day)
- E is the total energy (kJ)
- T is the total time (days)

To calculate Kilojoules Per Day, divide the energy in kilojoules by the time in days.

## How to Calculate Kilojoules Per Day?

The following steps outline how to calculate the Kilojoules Per Day.

- First, determine the total energy (kJ).
- Next, determine the total time (days).
- Next, gather the formula from above = KJD = E / T.
- Finally, calculate the Kilojoules Per Day.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

total energy (kJ) = 5000

total time (days) = 6

## Frequently Asked Questions (FAQ)

**What is a kilojoule and how is it related to calories?**

A kilojoule (kJ) is a unit of energy in the metric system. It is widely used to express the energy content of food outside of the United States, where calories are more commonly used. 1 kilojoule is approximately equal to 0.239 calories, meaning that if you want to convert kilojoules to calories, you multiply the kilojoules by 0.239.

**Why is it important to calculate kilojoules per day?**

Calculating kilojoules per day is essential for managing energy intake and expenditure for weight management or to ensure adequate energy supply for daily activities and bodily functions. It helps individuals adjust their diet and activity levels to meet their health and fitness goals.

**How can understanding kilojoules per day help in weight management?**

Understanding and monitoring kilojoules per day can help in weight management by providing a measure of the energy consumed through food and drink versus the energy expended through physical activity and basic bodily functions. By balancing the energy intake and expenditure, individuals can aim for weight loss, gain, or maintenance, depending on their goals.

**Are there tools or apps that can help track kilojoules intake and expenditure?**

Yes, there are many tools and apps available that can help track kilojoules intake and expenditure. These tools often include databases of food and activities to make logging and calculating easier. They can provide insights into your daily energy balance, helping you make informed decisions about your diet and activity levels.
