Convert ft to meter: Simple Formula, Examples, and Pro Tips
Converting measurements should be fast, accurate, and easy. If you need to convert ft to meter for school, work, or DIY projects, this guide gives you the exact formula, helpful tips, and real examples. We keep it simple: one foot equals 0.3048 meters, exactly. Read on for quick math, tables, and best practices.
Quick Answer (Featured Snippet)
- To convert ft to meter, multiply feet by 0.3048. The formula is: meters = feet × 0.3048. Example: 10 ft × 0.3048 = 3.048 m. For feet and inches, first convert inches to feet (in ÷ 12), add to feet, then multiply by 0.3048. This value (0.3048) is exact, set by international standard.
AI Overview (Quick Summary)
- The fastest way to convert feet to meters is to multiply by 0.3048. This exact conversion comes from the definition that 1 inch is exactly 2.54 cm. Use the formula m = ft × 0.3048, or for feet and inches: m = (ft + in/12) × 0.3048. You can round to the number of decimals you need (e.g., 2–3 decimals for general use). See the tables, examples, and FAQs below for common values and tips.
Key Takeaways
- Formula: meters = feet × 0.3048 (exact)
- Feet and inches: meters = (ft + in/12) × 0.3048
- Reverse: feet = meters ÷ 0.3048 (or meters × 3.28084)
- Round at the end to keep accuracy
- 1 m ≈ 3.281 ft; 6 ft ≈ 1.829 m; 10 ft ≈ 3.048 m
- Use 0.3048, not 0.305, for precise work
- Tables and examples help you check your math fast

What is convert ft to meter?
“Convert ft to meter” means changing a length measurement from feet (ft), used mostly in the U.S. and a few other places, to meters (m), the standard SI unit used worldwide.
- Exact conversion: 1 foot = 0.3048 meters
- This is not an approximation. It is exact by international agreement since 1959.
- Why exact? Because 1 inch = 2.54 centimeters exactly. There are 12 inches in a foot. So, 1 ft = 12 × 2.54 cm = 30.48 cm = 0.3048 m.
Core formulas:
- meters = feet × 0.3048
- feet = meters ÷ 0.3048 (or meters × 3.28084)
Related terms you might see:
- “feet to meters,” “ft to m,” “convert feet and inches to meters,” “metric conversion,” “SI units.” These all refer to the same process.
Why it Matters
- Global work: Engineering, construction, and science teams often share plans in meters.
- Travel and sports: Track lengths, hiking routes, and altitude are measured in meters.
- Building codes: Many standards and materials use metric specs.
- Education: Science and math classes use SI units.
- Accuracy: Using the exact factor (0.3048) avoids costly errors.
In short, knowing how to convert ft to meter helps you communicate clearly and measure accurately, anywhere.
Benefits
- Accuracy: The 0.3048 factor is exact, so your results are dependable.
- Speed: A single multiplication gets you from ft to m fast.
- Fewer errors: Clear steps and unit labels reduce mistakes.
- Better teamwork: Share consistent measurements across countries and fields.
- Smarter planning: Pick materials, sizes, and distances with confidence.
Step-by-Step Guide
Follow these steps to convert feet to meters correctly every time.
- Know the exact factor
- 1 ft = 0.3048 m (exact)
- Keep this factor at full precision for accurate results.
- Convert feet to meters (simple numbers)
- Formula: meters = feet × 0.3048
- Example: 10 ft × 0.3048 = 3.048 m
- Convert feet and inches to meters
- Step A: Convert inches to feet: inches ÷ 12
- Step B: Add to feet: total feet = ft + (in ÷ 12)
- Step C: Multiply by 0.3048
- Example: 5 ft 9 in
- 9 in ÷ 12 = 0.75 ft
- Total feet = 5 + 0.75 = 5.75 ft
- Meters = 5.75 × 0.3048 = 1.7526 m
- Rounding tips
- Round at the end of your calculation, not during it.
- Common choices:
- Everyday use: 2 decimals (e.g., 1.75 m)
- Construction/fabrication: centimeters (2 decimals) or millimeters (3 decimals)
- Science/engineering: base it on significant figures in your original measurement
- Quick check with reverse math
- Multiply your meter result by 3.28084 to get feet again. If it matches your start value (within rounding), you’re good.
- Spreadsheet method (Excel/Google Sheets)
- Feet in A2: =A2*0.3048
- Feet and inches in A2 and B2: =(A2 + B2/12)*0.3048
- Set cell format to desired number of decimals.
- Mental math method
- Multiply by 0.3, then add about 1.6% more (because 0.3048 − 0.3 = 0.0048 ≈ 1.6% of 0.3×ft value)
- Example: 20 ft → 20 × 0.3 = 6; 6 × 0.016 ≈ 0.096; total ≈ 6.096 m (exact is 6.096 m)
- Unit labels
- Always write units in your work (ft, m) to avoid mixing them up.
Real World Examples
- Room length
- 12 ft → 12 × 0.3048 = 3.6576 m → 3.66 m (rounded)
- Person’s height (6 ft 2 in)
- 6 ft 2 in → 2 in ÷ 12 = 0.1667 ft → total feet = 6.1667 ft
- Meters = 6.1667 × 0.3048 ≈ 1.8796 m → 1.88 m
- Workbench size
- 5 ft → 5 × 0.3048 = 1.524 m → 1.52 m (if rounding to 2 decimals)
- Garden path
- 25 ft → 25 × 0.3048 = 7.62 m
- Pool length
- 50 ft → 50 × 0.3048 = 15.24 m
- Cable run
- 100 ft → 100 × 0.3048 = 30.48 m
- Hiking sign (3.5 ft post height)
- 3.5 × 0.3048 = 1.0668 m → 1.07 m
- Ceiling height (8 ft)
- 8 × 0.3048 = 2.4384 m → 2.44 m
- TV mounting (5 ft 9 in from floor)
- 5.75 ft × 0.3048 = 1.7526 m → 1.75 m
- Warehouse aisle (14 ft)
- 14 × 0.3048 = 4.2672 m → 4.27 m
These examples show the range: from home projects to professional work, the same exact factor applies.
Common Mistakes
- Using 3.28 instead of 0.3048 for ft → m
- 3.28 is the factor for m → ft, not ft → m.
- Rounding too early
- Keep 0.3048 through the calculation; round only the final answer.
- Mixing feet and inches without converting inches to feet first
- Always do in ÷ 12, then add to feet.
- Confusing linear feet with square feet or cubic feet
- Each has its own factor:
- Area: 1 ft² = 0.09290304 m²
- Volume: 1 ft³ = 0.028316846592 m³
- Dropping unit labels
- Write ft and m so you (and others) know which is which.
- Copying rounded factors from memory (like 0.305)
- For high precision, use 0.3048 exactly.
Best Practices
- Memorize the exact factor: 1 ft = 0.3048 m
- Keep units with every number while calculating
- Round at the end, and match the precision to your job
- Double-check with the reverse conversion (× 3.28084)
- Use a trusted converter for speed and consistency
- For documents or code, note the source of your factor (e.g., NIST)
- Add a safety margin when measurements affect fit or load
Expert Tips
- Anchor values to remember:
- 3 ft ≈ 0.9144 m (almost 1 m)
- 6 ft ≈ 1.829 m (about 1.83 m)
- 10 ft = 3.048 m
- 100 ft = 30.48 m
- Fast mental conversion:
- ft × 0.3, then add about 1.6% more to refine.
- Spreadsheet-friendly:
- Use named cells (e.g., Factor = 0.3048) so your formulas are readable.
- Engineering drawing tip:
- Note which unit system is the “master.” Convert only when needed to avoid stacking rounding errors.
- Quality control:
- If multiple people convert values, standardize rounding rules and document them.
