Answer

Health application: compute BMI Program code:

# Prompt the user to enter weight in pounds
weightPounds = float(input("Enter weight in pounds: "))

# Prompt the user to enter height in inches
heightInches = float(input("Enter height in inches: "))

# Convert weight from pounds to kilograms
weight_kg = weightPounds * 0.45359237

# Convert height from inches to meters
height_meters = heightInches * 0.0254

# Calculate the BMI by dividing weight in kilograms by the square of height in meters
bmi = weight_kg / (height_meters ** 2)

# Display the calculated BMI
print("BMI is", '{0:.4f}'.format(bmi))

Executed Output:

Enter weight in pounds: 95.5
Enter height in inches: 50
BMI is 26.8573
