Centimeters
The “Centimeters” value used in this tool’s formula. Adjust it to see results update live.
inches = centimeters ÷ 2.54.
Height charts, inseam tables, and sewing patterns swap cm and inches constantly. Divide cm by 2.54. A 180 cm person is about 5 ft 11 in — the leftover 0.16 in is why both sides of a doorway argue about the last fraction.

- Bra Size ConverterBand in inches (US/UK) and cup letter. EU bands are centimeters rounded to 5 (34 → 75). Cup letters drift after D: UK DD vs US DD/E is a forum war. Sister sizes (34C / 32D) share cup volume, not this converter’s job.
- Cubic Inches to Cubic CentimetersEngine displacement: a “350” small-block is 350 in³, about 5.7 L (5,735 cc). Multiply in³ by 16.387. One liter is 1,000 cm³. This is why 5.0 L and 302 in³ show up on the same valve cover.

A 5K is 5,000 meters, not 5 kilometers on the nose if your watch is sloppy. Divide meters by 1,000. Track races, building plans, and “how far was that hike” all live in this split.
Feet to Meters
Unit Converters
US height, ceiling height, and lumber still arrive in feet. Meter plans do not. One foot is exactly 0.3048 m — not “about a third.” Use this when a listing says 10 ft ceilings and the architect works in meters.
