Feet to Meters Converter: Formula & Examples

This calculator converts a length from feet to meters. Enter the number of feet, and you get the equivalent length in meters, plus the reverse conversion for reference. The conversion is exact: 1 foot equals 0.3048 meters.

Formula

The relationship between feet and meters is defined by international agreement. The formula is:

meters = feet × 0.3048

Where:

• feet is the length in feet (unit: ft)
• meters is the resulting length in meters (unit: m)
• 0.3048 is the exact conversion factor (unit: m/ft)

To go the other way, divide by 0.3048: feet = meters ÷ 0.3048.

Worked Example

Using the default value of 10 feet:

1. Start with 10 ft.
2. Multiply by the conversion factor: 10 × 0.3048 = 3.048.
3. Round to two decimal places: 3.05 m.

The calculator shows 3.05 m for 10 ft, matching the step-by-step result.

Why 0.3048? A Short History

The foot has been used for thousands of years, but its length varied by country and era. The modern definition was fixed in 1959 when English-speaking nations agreed to standardize the foot as exactly 0.3048 meters. Before that, the U.S. and the British Commonwealth used slightly different values (differing by about 2 parts per million). Today, the international foot is the standard used in aviation, engineering, and everyday measurements in the U.S., while most of the world uses the meter.

This agreement also defined the inch as exactly 2.54 centimeters, which is why 1 foot = 12 inches × 2.54 cm = 30.48 cm = 0.3048 m.

How to Convert Feet to Meters Manually

If you don’t have a calculator handy, here’s a simple method:

• Exact method: Multiply the number of feet by 0.3048. For example, 6 ft × 0.3048 = 1.8288 m.
• Quick mental estimate: Divide the feet by 3, then subtract 10%. For 6 ft: 6 ÷ 3 = 2, minus 0.2 = 1.8 m (close to 1.83 m).
• Rough rule of thumb: 1 meter ≈ 3.28 feet, so a foot is a bit less than a third of a meter.

For most everyday purposes, rounding to two decimal places is sufficient. For engineering or scientific work, use the full 0.3048 factor and keep more digits.

Common Mistakes and How to Avoid Them

The most frequent error is using the wrong direction: dividing when you should multiply, or vice versa. Remember:

• Feet are smaller than meters (1 ft ≈ 0.3 m), so the number of meters should be less than the number of feet. If you get a larger number, you divided instead of multiplied.
• Mixing up with inches: 1 inch = 0.0254 m, not 0.3048. If you have inches, convert to feet first (divide by 12) or use the inch factor directly.
• Forgetting to round consistently: if you round intermediate steps, the final answer may be off. Do the calculation in one go, then round.

When to Use This Conversion

You’ll need feet-to-meters conversion in many real situations:

• Travel and maps: Hiking trail distances, flight altitudes (e.g., 10,000 ft to meters).
• Construction and DIY: Room dimensions, lumber lengths, ceiling heights.
• Sports: Track and field events (e.g., 100-yard dash ≈ 91.44 m), swimming pool lengths.
• Education: Physics and math problems using SI units.
• Online shopping: Product dimensions listed in feet.

In countries that use the metric system, meters are the standard for these contexts, so conversion is essential for understanding measurements from the U.S. or the UK.

Limits of the Formula

The conversion factor 0.3048 is exact, so the formula itself has no error. The only limitations come from:

• Input precision: If you enter a rounded number of feet (e.g., 10 ft instead of 10.25 ft), the output is only as precise as the input.
• Rounding the output: The calculator rounds to two decimal places by default. For high-precision work, increase the decimal places or use the full value.
• Context: In some fields, like aviation, altitude is given in feet even in metric countries. Always check the unit expected in your specific application.

Frequently Asked Questions

How many meters is 1 foot?

Exactly 0.3048 meters. That’s about 30.48 centimeters, or just over 12 inches.

How many feet are in a meter?

One meter equals approximately 3.28084 feet. To convert meters to feet, multiply by 3.28084, or divide by 0.3048.

What is the difference between a foot and a meter?

A meter is the base unit of length in the International System of Units (SI), defined as the distance light travels in 1/299,792,458 of a second. A foot is a unit in the imperial and U.S. customary systems, now defined as exactly 0.3048 meters. A meter is about 3.28 feet, so it’s longer than a foot.

How do I convert feet to meters in my head?

Divide the number of feet by 3 to get a rough estimate, then subtract 10%. For example, 100 ft ÷ 3 = 33.3, minus 3.3 = 30 m (exact is 30.48 m). For a more precise mental math, multiply by 0.3 and add 1.6% of the result.

Is 1 meter exactly 3 feet?

No, 1 meter is about 3.28 feet. Three feet is 0.9144 meters, which is slightly less than a meter. This rounding error can cause noticeable mistakes over long distances.

Why do some countries still use feet?

The U.S., Myanmar, and Liberia are the only countries that officially use the imperial system. The U.S. has a large infrastructure and cultural attachment to feet and inches, and metric conversion efforts have been slow. Aviation and some industries also use feet globally for consistency.
