Feet to Meters Calculator: Instant Conversion

This feet-to-meters calculator converts a length or distance given in feet (and optionally inches) into its equivalent in meters. Enter your value in feet, and the calculator returns the result in meters, rounded to your chosen number of decimal places. It also shows the exact conversion factor used, so you can verify the math yourself.

Formula

The conversion from feet to meters is based on the international yard and pound agreement of 1959, which defines one foot as exactly 0.3048 meters. The formula is:

meters = feet × 0.3048

If you also have inches, first convert them to feet by dividing by 12, then apply the same factor:

meters = (feet + inches/12) × 0.3048

Where:

• feet – the whole-foot part of your measurement (unit: ft)
• inches – the additional inches beyond the whole feet (unit: in, 1 ft = 12 in)
• meters – the resulting length in the metric system (unit: m)

For reference, 1 meter equals approximately 3.28084 feet, so the inverse conversion is feet = meters × 3.28084.

Worked Example

Using the calculator defaults: 10 feet and 0 inches.

1. Convert inches to feet: 0 in ÷ 12 = 0 ft
2. Total feet = 10 + 0 = 10 ft
3. Multiply by the conversion factor: 10 × 0.3048 = 3.048 m
4. Rounded to 2 decimal places: 3.05 m

The calculator displays 3.05 m as the headline result, and 304.8 cm (3.048 × 100) as the secondary output.

Why Convert Feet to Meters?

The United States, Myanmar, and Liberia are the only countries that still use the imperial system as their official standard. Almost everywhere else, including all scientific and engineering contexts, uses the metric system. You might need to convert feet to meters when:

• Reading a product spec from a US supplier that lists dimensions in feet.
• Planning a hike or run using a map that shows elevations in feet but you think in meters.
• Buying fabric, rope, or cable sold by the foot but you need a metric length.
• Converting a person’s height (often given as 5’10”) for a medical form or international driver’s license.
• Working on a construction project that mixes US and metric drawings.

Because the conversion is a fixed constant, there is no ambiguity—0.3048 is exact, not an approximation.

How to Read the Result

The calculator gives meters as a decimal number (e.g., 3.05 m). If you need centimeters, multiply the meter value by 100. For instance, 3.05 m equals 305 cm. If you need millimeters, multiply by 1000.

For heights, a result like 1.83 m is common. To express that in feet and inches, take the decimal part (0.83) and multiply by 39.37 to get inches: 0.83 × 39.37 ≈ 32.7 inches, which is 2 feet 8.7 inches—so 1.83 m ≈ 6 ft 0 in. The calculator’s secondary output in centimeters helps with that.

For very large distances (miles to kilometers), you’d use a different factor, but feet-to-meters works for most everyday lengths like room dimensions, furniture, and athletic field measurements.

Common Mistakes and How to Avoid Them

• Forgetting the 12 inches per foot: If you enter 5 ft 10 in as just 5.10 feet, you get 1.55 m instead of 1.78 m. Always divide inches by 12 before adding to feet.
• Using the wrong conversion factor: Some people mistakenly use 0.3 or 3.28. Use 0.3048 exactly for precise work.
• Rounding too early: If you round 0.3048 to 0.3, a 100-foot distance becomes 30 m instead of 30.48 m—a 1.6% error. Keep at least 4 decimal places during intermediate steps.
• Confusing meters with centimeters: A common slip is reading 3.05 m as 3.05 cm. The calculator’s separate cm output helps you avoid that.
• Mixing units in the same expression: If you add feet and inches directly (e.g., 5 + 10 = 15) you’ll get nonsense. Always convert inches to feet first.

Limits of the Formula

The conversion is exact for all practical purposes, but there are a few nuances:

• Precision: The international foot is defined as exactly 0.3048 m, so no measurement uncertainty comes from the conversion itself. Any error comes from your original measurement.
• Survey foot: In the United States, a separate “US survey footâ€� (0.3048006096 m) was used for land surveying until 2022. It differs from the international foot by about 2 parts per million. For most everyday uses, the difference is negligible, but for large land surveys it can add up. The calculator uses the international foot, which is the current standard.
• Negative values: The calculator allows negative inputs (e.g., -5 ft) because lengths can be negative in coordinate systems. The conversion works the same way.
• Very large numbers: If you enter a huge number (like 10^15 feet), the result may be displayed in scientific notation. That’s fine, but be aware of the unit scale.

Alternatives to This Calculator

If you need to convert between other units, you have several options:

• Online converters: Many websites offer unit conversion tools for free. This calculator is one of them, but you can also use search engines by typing “10 feet in metersâ€� and getting an instant answer.
• Smartphone apps: Unit converter apps are available for iOS and Android, often with offline capability.
• Spreadsheets: In Excel or Google Sheets, use the CONVERT function: =CONVERT(10,"ft","m") returns 3.048.
• Mental math: For rough estimates, remember that 1 foot is about 0.3 meters, so 10 ft ≈ 3 m. For more accuracy, multiply by 0.3048.

Frequently Asked Questions

How many meters are in a foot?

One foot is exactly 0.3048 meters. This is an international standard, so it’s the same everywhere. For a quick mental estimate, 1 foot is about 30 centimeters, or roughly one-third of a meter.

How do I convert feet and inches to meters without a calculator?

First, convert inches to feet by dividing by 12. Add that to the whole feet. Then multiply the total by 0.3048. For example, 5’10” = (5 + 10/12) = 5.8333 ft, then 5.8333 × 0.3048 = 1.778 m. If you prefer, you can also convert the total to inches (5×12+10=70 in) and multiply by 0.0254 (since 1 inch = 0.0254 m).

Is a meter longer than a foot?

Yes, a meter is longer than a foot. One meter equals about 3.28 feet. So if you have a measurement in feet, the number in meters will be smaller. For example, 10 feet is only about 3.05 meters.

What is the difference between a foot and a square foot?

A foot is a unit of length (one dimension). A square foot is a unit of area (two dimensions), equal to a square that is 1 foot on each side. To convert square feet to square meters, you multiply by 0.092903 (which is 0.3048 squared). This calculator only handles linear feet, not area.

Why is the conversion factor 0.3048 and not a round number?

It comes from the 1959 international agreement that defined the yard as exactly 0.9144 meters. Since there are 3 feet in a yard, one foot is 0.9144 ÷ 3 = 0.3048 meters. The number is exact, not an approximation.

Can I use this calculator for height?

Yes. Enter feet in the first box and inches in the second. For example, 6 feet 0 inches gives 1.83 m. This is a common way to convert human height for medical records or international forms. The calculator’s centimeter output is especially handy because many countries use cm for height.
