Trick 2: Mental Math Shortcuts

While precise conversions are necessary in some cases, for quick estimations, mental math can save the day:

• Divide by 2.54: Since 1 inch is exactly 2.54 cm, you can mentally divide 68 by 2.5:
  • ( 68 \div 2.5 \approx 27.2 ) (To make this simpler, you can multiply 68 by 2 then divide by 5.)

Result: This method gets you to roughly 27.2 inches, a close estimate to the exact conversion.

Trick 3: Use a Conversion Table or Chart
