• Trick 2: Think in terms of doubling and halving.

  • 120 inches (10 feet) + 18 inches (1.5 feet) = 11.5 feet.

• Not Converting Back and Forth: Check your conversion by reversing the process to catch any errors.

• Misinterpreting Unit Symbols: Ensure you're not mixing up inches ('in' or '") with other units like feet ('ft' or ''')

Troubleshooting Common Conversion Issues
