MM to Feet Converter (mm → ft): millimeters to feet & inches
Our MM to Feet Converter gives instant, accurate results using the official definitions (1 inch = 25.4 mm, 1 foot = 304.8 mm). It’s perfect for construction, woodworking, DIY, and product sizing—showing clean decimal feet and, when needed, feet + inches for tape-measure work. The rule is simple: feet = mm ÷ 304.8. For feet + inches, first find total inches (in = mm ÷ 25.4), then split into feet = floor(in ÷ 12) and inches = in − feet×12 (round to a friendly fraction like 1/16). Example: 1,800 mm → 1,800 ÷ 304.8 = 5.90551… ≈ 5.906 ft, which is about 5 ft 10 7/8 in.
- 1 inch = 25.4 mm (exact)
- 1 foot = 12 inches = 304.8 mm (exact)
From these definitions:
- Feet (ft) = Millimeters (mm) ÷ 304.8
- Inches (in) = Millimeters (mm) ÷ 25.4 → then split inches into feet + inches if you want tape-measure style.

Quick answer (snippet-friendly)
How to convert mm to feet?
Use ft = mm ÷ 304.8.
Examples (accurate):
- 1,000 mm → 3.28084 ft
- 1,500 mm → 4.92126 ft
- 3,000 mm → 9.84252 ft
Feet + inches method:
- Total inches: in = mm ÷ 25.4
- Feet: ft = floor(in ÷ 12)
- Inches (remainder): inches = in − ft × 12
- Round inches to a simple fraction (e.g., 1/16) for tape-friendly output.
What are millimeters and feet?
Millimeter (mm) is a metric unit for small, precise sizes—hardware, 3D prints, PCB spacing, trim gaps. 1 mm = 0.001 m and 1 m = 1,000 mm.
Foot (ft) is an imperial / US customary unit used on job sites, in architecture, and with tape measures. 1 ft = 12 in = 304.8 mm (exact). Converting between mm and feet is common in construction, renovation, metalwork, and woodworking.
Exact formulas (no guesswork)
Because the inch and foot are defined exactly in millimeters, you can rely on exact factors:
ft = mm ÷ 304.8
in = mm ÷ 25.4
mm = ft × 304.8
mm = in × 25.4
Step-by-step examples
A) mm → decimal feet
Example: 1,800 mm
- Apply: ft = 1,800 ÷ 304.8 = 5.90551…
- Display (3 decimals): 5.906 ft
Example: 2,200 mm
- ft = 2,200 ÷ 304.8 = 7.21785… → 7.218 ft
B) mm → feet + inches (nearest 1/16)
Example: 1,800 mm
- in = 1,800 ÷ 25.4 = 70.866… in
- ft = floor(70.866 ÷ 12) = 5 ft
- inches remainder = 70.866 − 60 = 10.866 in
- Fraction: 0.866 × 16 ≈ 13.86 → 14/16 = 7/8
Result: ≈ 5 ft 10 7/8 in
Carry rules:
- If fraction rounds to 16/16, add 1 inch and reset fraction to 0.
- If inches become 12, add 1 foot and set inches to 0.
When to show decimal feet vs feet + inches
- Decimal feet → clean for specs, CAD, spreadsheets, and product pages.
- Feet + inches → best for measuring, cutting, site notes, and communicating with pros who use tape measures.
Consider offering both formats: users can see decimal ft for math and ft + in to actually cut or fit parts.

Mistakes to avoid (save time & rework)
- Over-rounding the factor as “0.0033 ft/mm.”
Use the exact definition: 1 ft = 304.8 mm → 1 mm ≈ 0.00328084 ft. - Rounding too early.
Keep full precision in calculations and round once at the end. - Mixing cm with mm.
2.54 is for cm ↔ in, not mm ↔ ft. For mm use 25.4 (inches) or 304.8 (feet). - Forgetting fraction carry.
If fractional inches round to 16/16, add 1 inch; if inches hit 12, add 1 foot.
Related conversions you may need
- mm ↔ inches: in = mm ÷ 25.4; mm = in × 25.4
- mm ↔ cm: cm = mm ÷ 10; mm = cm × 10
- mm ↔ m: m = mm ÷ 1000; mm = m × 1000
- ft ↔ m: m = ft × 0.3048; ft = m ÷ 0.3048
