Python program to calculate BMI(Body Mass Index) of your Body

Body Mass Index (BMI) is a measure used to determine whether a person has a healthy body weight for their height. The BMI formula is: BMI = weight (kg) / height² (m²).

Algorithm

Step 1: Input height in meters and weight in kilograms
Step 2: Apply the BMI formula: weight / (height × height)
Step 3: Display the calculated BMI value
Step 4: Interpret the BMI category

Basic BMI Calculator

Here's a simple program to calculate BMI −

height = float(input("Enter your height (m): "))
weight = float(input("Enter your weight (kg): "))
bmi = round(weight / (height * height), 2)
print("Your BMI is:", bmi)

Enter your height (m): 1.75
Enter your weight (kg): 70
Your BMI is: 22.86

BMI with Health Categories

This enhanced version also shows the BMI category −

height = float(input("Enter your height (m): "))
weight = float(input("Enter your weight (kg): "))
bmi = round(weight / (height * height), 2)

print(f"Your BMI is: {bmi}")

if bmi < 18.5:
    print("Category: Underweight")
elif bmi < 25:
    print("Category: Normal weight")
elif bmi < 30:
    print("Category: Overweight")
else:
    print("Category: Obese")

Enter your height (m): 1.75
Enter your weight (kg): 70
Your BMI is: 22.86
Category: Normal weight

Conclusion

BMI is calculated using the formula weight / height². While BMI is a useful screening tool, consult healthcare professionals for comprehensive health assessment as BMI doesn't account for muscle mass or body composition.
