Centimeters ↔ Feet & Inches
Forward converts cm to total inches, then splits into whole feet and remaining inches. Reverse rebuilds cm from feet and inches.
Limitation: Uses the exact international inch (2.54 cm).
How to Convert Height Units
For metric → imperial, enter centimeters. For imperial → metric, enter whole feet and inches under 12.
Choose centimeters → feet & inches or the reverse.
Inches under 12
In reverse mode inches must be less than 12; carry extra inches into feet first.
What the Split Means
Forward converts cm to total inches, then splits into whole feet and remaining inches. Reverse rebuilds cm from feet and inches.
