Python Program to Read Height in Centimeters and convert the Height to Feet and Inches

Converting height from centimeters to feet and inches is a common unit conversion task. Python provides built-in functions like round() to handle decimal precision in calculations.

Basic Conversion Method

Here's a simple approach to convert centimeters to both feet and inches separately ?

height_cm = int(input("Enter the height in centimeters: "))

# Convert to inches and feet
height_inches = 0.394 * height_cm
height_feet = 0.0328 * height_cm

print("The height in inches is:", round(height_inches, 2))
print("The height in feet is:", round(height_feet, 2))

Enter the height in centimeters: 178
The height in inches is: 70.13
The height in feet is: 5.84

Converting to Feet and Remaining Inches

A more practical approach is to express height in feet and remaining inches format ?

height_cm = 178

# Convert to total inches first
total_inches = height_cm / 2.54

# Calculate feet and remaining inches
feet = int(total_inches // 12)
remaining_inches = round(total_inches % 12, 1)

print(f"Height: {height_cm} cm")
print(f"Converted: {feet} feet {remaining_inches} inches")

Height: 178 cm
Converted: 5 feet 10.1 inches

Comparison of Methods

Key Conversion Factors

• 1 inch = 2.54 cm (exact conversion)

• 1 foot = 12 inches = 30.48 cm

• 0.394 factor is an approximation (1÷2.54)

• 0.0328 factor is an approximation (1÷30.48)

Complete Example with Input Validation

try:
    height_cm = float(input("Enter height in centimeters: "))
    
    if height_cm <= 0:
        print("Height must be positive!")
    else:
        # More accurate conversion
        total_inches = height_cm / 2.54
        feet = int(total_inches // 12)
        inches = round(total_inches % 12, 1)
        
        print(f"\nHeight conversion:")
        print(f"{height_cm} cm = {feet}' {inches}"")
        print(f"Total inches: {round(total_inches, 1)}")
        print(f"Decimal feet: {round(total_inches / 12, 2)}")
        
except ValueError:
    print("Please enter a valid number!")

Enter height in centimeters: 175
  
Height conversion:
175.0 cm = 5' 8.9"
Total inches: 68.9
Decimal feet: 5.74

Conclusion

Use the feet-and-inches format for practical applications, as it's more intuitive. The exact conversion factor is 1 inch = 2.54 cm, which provides more accurate results than the approximation factors.
