Ft to Meters Calculator: Quick Conversion

This calculator converts feet to meters instantly. Enter a length in feet and get the equivalent in meters. The conversion uses the standard factor 1 foot = 0.3048 meters exactly.

Formula

The conversion is a simple multiplication:

meters = feet × 0.3048

• feet – the length you want to convert, in feet (ft)
• 0.3048 – the exact number of meters in one foot
• meters – the resulting length, in meters (m)

The factor 0.3048 is defined by international agreement (the international yard and pound agreement of 1959). It is exact, not an approximation. For reverse conversion (meters to feet), divide by 0.3048 or multiply by 3.28084.

Worked Example

Using the default value of 10 feet:

1. Start with 10 ft.
2. Multiply by 0.3048: 10 × 0.3048 = 3.048.
3. Result: 3.048 meters.

The calculator rounds to 4 decimal places, so it shows 3.0480 m. If you need fewer decimals, just round yourself: 3.05 m is fine for most practical purposes.

Why Use Feet and Meters?

Feet are part of the US customary system, used mainly in the United States, Myanmar, and Liberia. Meters are the base unit of length in the International System of Units (SI), used almost everywhere else in the world. Even in the US, many fields—science, medicine, engineering, and international trade—use meters. So conversion is common whenever you read a foreign specification, travel, or work with global standards.

The foot is also used in aviation (altitude) and in some construction contexts, while meters dominate in most other technical work. Knowing both helps you compare measurements from different sources without error.

Common Mistakes and How to Avoid Them

• Using the wrong factor: Some people use 0.3 as a shortcut. That gives a rough estimate but can be off by about 1.6%—for a 100 ft length, the error is 0.48 m (about 1.6 ft). Use 0.3048 for accuracy.
• Mixing up feet and inches: 5 ft 10 in is not 5.10 ft. Convert inches first: 10 in ÷ 12 = 0.833 ft, so total is 5.833 ft. Then multiply by 0.3048.
• Forgetting to convert square or cubic feet: 1 square foot = 0.092903 m², not 0.3048 m². For volume, 1 cubic foot = 0.0283168 m³. The linear factor must be squared or cubed.
• Rounding too early: If you round 0.3048 to 0.3 before multiplying, you lose precision. Do the multiplication first, then round the final answer.

How to Convert Without a Calculator

If you need a quick mental estimate, multiply the number of feet by 0.3 and then add 0.0048 times the number of feet. For example, 10 ft: 10 × 0.3 = 3, plus 10 × 0.0048 = 0.048, total 3.048 m. That works because 0.3048 = 0.3 + 0.0048.

For a slightly rougher estimate, just multiply by 0.3. It’s within 2% for any length. If you’re converting meters to feet in your head, multiply by 3.28 (or roughly 3.3).

Practical Examples

• Room dimensions: A room 12 ft × 14 ft is 3.66 m × 4.27 m. Area in square feet is 168, but in square meters it’s 15.6 m² (not 168 × 0.3048).
• Height: 6 ft tall is 1.8288 m, usually rounded to 1.83 m. Many countries list height in centimeters: 183 cm.
• Running track: A 100-yard football field is 300 ft, which is 91.44 m. A 100 m dash is about 109.36 yards.
• Construction: A 2×4 board is actually 1.5 in × 3.5 in, which is 3.81 cm × 8.89 cm. Lumber sizes are nominal, so always check actual dimensions.

Limits of the Conversion

This conversion is exact and universal. The only limitation is the number of decimal places you choose. For everyday use, 2–4 decimals are enough. For scientific work, you may need more precision, but the factor 0.3048 is exact, so any difference comes from rounding the output.

Remember that the foot has been defined as exactly 0.3048 m since 1959. Before that, different countries had slightly different foot lengths (e.g., US survey foot was 1200/3937 m, about 0.3048006 m). If you are working with very old land records, there might be a tiny discrepancy, but for virtually all modern purposes, 0.3048 is correct.

Frequently Asked Questions

How many meters is 5 feet?

5 feet × 0.3048 = 1.524 meters. That’s about 152.4 cm, which is a common height for a person.

How do I convert feet and inches to meters?

First convert inches to feet by dividing by 12. Add that to the whole feet, then multiply by 0.3048. For example, 5 ft 10 in: 10/12 = 0.8333, so 5.8333 ft × 0.3048 = 1.778 m.

Is 1 meter exactly 3.28 feet?

Yes, 1 meter = 3.28084 feet. The exact value is 1/0.3048, which is a repeating decimal (3.280839895…). For most purposes, 3.28 is close enough, but for precise work use more decimals.

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

A foot measures length (1D). A square foot measures area (2D). To convert square feet to square meters, multiply by 0.092903 (which is 0.3048²). Do not use the linear factor for area conversions.

Why is the conversion factor 0.3048?

It was defined in 1959 by an international agreement among English-speaking countries to standardize the yard as exactly 0.9144 meters, making the foot exactly one-third of that, or 0.3048 meters.
