This calculator converts a length from feet to meters instantly. Enter the number of feet (including fractional feet, such as 5.5), and the tool returns the equivalent length in meters, rounded to two decimal places. The conversion uses the exact international standard: 1 foot = 0.3048 meters.
Formula
The conversion is a single multiplication:
meters = feet × 0.3048
Where:
- feet (ft) is the length you input, a unit in the US customary and imperial systems.
- meters (m) is the result, the base unit of length in the International System of Units (SI).
- 0.3048 is the exact conversion factor, defined by international agreement in 1959. It means one foot is exactly 0.3048 meters.
Worked Example
Using the default value of 10 feet:
- Start with the input: 10 ft.
- Multiply by the conversion factor: 10 × 0.3048.
- Compute: 10 × 0.3048 = 3.048.
- Round to two decimals: 3.05 m.
The calculator shows 3.05 m for 10 feet, matching the step-by-step result.
Why 0.3048? A Short History
Before 1959, the foot was defined differently in various countries. The US used a slightly longer “US survey foot� (0.3048006096 m), while the UK and Commonwealth used the “imperial foot� (0.3047990 m). This caused small errors in engineering and scientific work. In 1959, the US, UK, Canada, Australia, New Zealand, and South Africa signed the International Yard and Pound Agreement, fixing the international foot at exactly 0.3048 meters. The US survey foot was deprecated in 2022, and the international foot is now the standard for nearly all purposes.
How to Convert Feet to Meters Without a Calculator
If you need a quick mental estimate, use these approximations:
- Rough estimate: divide the number of feet by 3. Because 1 meter ≈ 3.28 feet, dividing by 3 gives a close value (e.g., 10 ft ÷ 3 ≈ 3.33 m, vs. actual 3.05 m – about 9% high).
- Better estimate: multiply feet by 0.3, then add 1.6% of the original feet. For 10 ft: 10 × 0.3 = 3.0, plus 0.16 = 3.16 m (still ~3.6% high).
- Exact mental trick: multiply feet by 3, then divide by 10, then adjust. For 10 ft: 10 × 3 = 30, ÷10 = 3.0, then add 0.048 (which is 0.3048 – 0.3 times 10) = 3.048 m. This is exact but requires remembering the factor.
For most everyday purposes, the rough estimate is fine. For construction, engineering, or scientific work, use the exact factor.
Common Mistakes and How to Avoid Them
- Using the wrong direction: To convert meters to feet, you divide by 0.3048, not multiply. A common error is multiplying both ways. Remember: feet are smaller than meters, so the number of meters should be smaller than the number of feet.
- Mixing up survey vs. international feet: For land surveying in the US, older data may use the US survey foot. The difference is tiny (about 1.6 mm per 1000 ft), but it can matter for large land parcels. Always check which definition your source uses.
- Rounding too early: If you convert 5 feet to meters and round to 1.52 m, then convert back, you get 4.99 ft. Keep extra digits during intermediate steps and round only at the end.
- Forgetting fractional feet: 5 feet 6 inches is 5.5 feet, not 5.6. Convert inches to feet by dividing by 12.
When to Use This Conversion
You need feet-to-meters conversion in many real situations:
- International travel and real estate: Property sizes in the US are often listed in square feet, while most of the world uses square meters. To convert area, convert the length and then square it, or use a dedicated area calculator.
- Sports: Track and field events are measured in meters internationally, but some US events still use feet (e.g., long jump in high school).
- Construction and DIY: Building materials may be sold in feet in the US but in meters elsewhere. Converting dimensions ensures correct ordering.
- Education: Science classes require consistent SI units, so physics and chemistry problems often need feet converted to meters.
- Aviation and maritime: Altitudes are often in feet, but some charts use meters. Pilots and sailors need quick, accurate conversions.
Feet vs. Meters: Which Is More Accurate?
Neither unit is inherently more accurate—accuracy depends on the measuring tool, not the unit. However, meters are part of the SI system, which is decimal-based, making calculations easier. Feet are divided into 12 inches, which is convenient for fractions (e.g., 1/3 of a foot is exactly 4 inches) but awkward for decimal math. The meter is defined by the speed of light, making it a fundamental physical constant, while the foot is defined relative to the meter. For scientific work, meters are preferred because they integrate with other SI units (e.g., seconds, kilograms). For everyday construction in the US, feet are standard because tools and materials are sized in feet and inches.
Frequently Asked Questions
How many feet are in a meter?
One meter equals approximately 3.28084 feet. To convert meters to feet, multiply by 3.28084. For a quick estimate, multiply by 3.3.
What is 6 feet in meters?
6 feet × 0.3048 = 1.8288 meters. Rounded to two decimals, that’s 1.83 m. This is a common height conversion.
How do I convert square feet to square meters?
You cannot use the linear conversion directly. Since area is length × width, you must convert each dimension to meters first, then multiply. Alternatively, multiply the square footage by 0.092903 (which is 0.3048²). For example, 100 sq ft × 0.092903 = 9.29 sq m.
Is a foot exactly 30.48 cm?
Yes. Since 1 meter = 100 cm, and 1 foot = 0.3048 m, then 1 foot = 30.48 cm exactly. This is useful for quick conversions to centimeters.
Why do some countries use feet while others use meters?
Historical adoption. The metric system was developed in France and spread globally during the 19th and 20th centuries. The US, Myanmar, and Liberia are the only countries that have not officially adopted the metric system as their primary system, though the US uses metric in science and many industries. The UK uses a mix: road signs in miles, but most weights and measures in metric.
What is the difference between a foot and a survey foot?
The international foot is exactly 0.3048 meters. The US survey foot was defined as 1200/3937 meters (approximately 0.3048006096 m). The survey foot is about 0.0000006096 m longer. In 2022, the US National Institute of Standards and Technology (NIST) deprecated the survey foot, but it may still appear in older land records.
