This tool calculates the daily calorie needs of a 9-year-old boy based on personalized input factors.
How to use the Calorie Calculator for 9-year-old Boys
Enter the weight in kilograms and height in centimeters of the boy in the respective fields. The age field is pre-filled to 9 years. Select the appropriate level of daily physical activity from the dropdown menu. Optionally, you can enter the Body Mass Index (BMI) if known.
After filling in the details, click the “Calculate” button. The calculator will compute the Basal Metabolic Rate (BMR) using the Mifflin-St Jeor equation and then multiply it by the selected activity level to determine the estimated daily caloric needs.
How the Calculation is Done
The Basal Metabolic Rate (BMR) is calculated using the Mifflin-St Jeor equation:
- BMR = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) + 5
The daily caloric needs are then estimated by multiplying the BMR by the activity level factor:
- Sedentary (little or no exercise): 1.2
- Lightly active (light exercise/sports 1-3 days/week): 1.375
- Moderately active (moderate exercise/sports 3-5 days/week): 1.55
- Very active (hard exercise/sports 6-7 days a week): 1.725
- Super active (very hard exercise/sports & a physical job): 1.9
