BMI calculator:
BMI is a quick and inexpensive way to categorize a person's weight as underweight, normal, overweight, or obese.
BMI formula:
BMI is calculated by dividing weight by height squared:
Metric units:
BMI = weight (kg) / [height (m)]2
US customary units:
BMI = weight (pounds) / [height (in)]2 x 703
Example:
# Input the weight in kilograms weight = float(input("Enter your weight (in kg): ")) # Input the height in meters height = float(input("Enter your height (in meters): ")) # Calculate BMI using the formula: bmi = weight / (height ** 2) # Output the calculated BMI value print("BMI:", round(bmi, 2)) # Rounds BMI to 2 decimal places # Function to provide feedback based on BMI def bmi_feedback(bmi): if bmi < 18.5: return "You are underweight" elif 18.5 <= bmi <= 24.9: return "You have a healthy weight" elif 25 <= bmi <= 29.9: return "You are overweight" else: return "You are obese" # Call the feedback function and store the result bmi_result = bmi_feedback(bmi) # Output the BMI category feedback print("BMI Result:", bmi_result)
Output:
Enter your weight:58 Enter your height:1.67 BMI: 20.796729893506402 BMI Result: You have a healthy weight
