The basic conversion: multiply feet by 0.3048

To convert feet to meters, multiply the number of feet by 0.3048. This single number is the conversion factor that turns any measurement in feet into its equivalent in meters. One foot equals exactly 0.3048 meters, so if you have 10 feet, you multiply 10 by 0.3048 to get 3.048 meters.

The math is straightforward: feet × 0.3048 = meters. You can do this on any calculator, in a spreadsheet, or by hand if you need only rough numbers. The conversion factor never changes, whether you are measuring a room, a piece of fabric, or a distance outdoors.

Key Takeaways

  • Multiply any measurement in feet by 0.3048 to get the same distance in meters.
  • For quick estimates, multiply by 0.3 instead of 0.3048 — you will be close enough for most everyday purposes.
  • If you need to go the other direction, divide meters by 0.3048 or multiply by 3.28084 to get feet.
  • Online converters and calculator apps can do the math for you if you prefer not to multiply by hand.

Working through a real example

Say you are looking at a room that is 12 feet long and need to know the length in meters. Take 12 and multiply it by 0.3048. The answer is 3.6576 meters. If you round to two decimal places (which is common for everyday measurements), the room is 3.66 meters long.

For a second example: a doorway that is 6.5 feet tall. Multiply 6.5 by 0.3048 and you get 1.98 meters, or roughly 2 meters. The more decimal places you keep in your answer, the more precise it is — but for most purposes, rounding to one or two decimal places is enough.

Quick mental math when you do not have a calculator

If you need a rough conversion without a calculator, use 0.3 instead of 0.3048. This is less precise but fast. Ten feet becomes roughly 3 meters (the exact answer is 3.048). Twenty feet becomes roughly 6 meters (exact: 6.096). You will be off by a small amount, but close enough for estimates.

Another shortcut: remember that 3 feet is almost exactly 1 meter (it is 0.9144 meters). So if you have a measurement in feet, divide it by 3 to get a rough meter equivalent. Twelve feet divided by 3 is 4 meters — the exact answer is 3.6576, so you are in the ballpark.

Converting meters back to feet

If someone gives you a measurement in meters and you need feet, the process reverses. Divide the meters by 0.3048, or multiply by 3.28084 (which is the reciprocal of 0.3048). So 5 meters divided by 0.3048 equals 16.404 feet. Or 5 meters times 3.28084 equals the same thing: 16.404 feet.

For a quick estimate going from meters to feet, multiply by 3.3. Five meters times 3.3 is 16.5 feet, which is very close to the exact answer of 16.404 feet.

Using online converters and apps

If you convert measurements often, an online converter saves time. Search "feet to meters converter" and you will find dozens of free tools where you type in a number and the conversion appears when ready. Many also work the other direction without extra steps. Calculator apps on phones usually have a built-in unit converter as well — open the app, look for a menu or settings option, and select "converter" or "units".

Spreadsheet programs like Excel or Google Sheets can also do the math for you. In a cell, type =A1*0.3048 (where A1 is the cell holding your feet measurement) and the program calculates meters automatically. This is useful if you have many measurements to convert at once.

Common situations where you need this conversion

You might need to convert feet to meters when reading building plans from other countries, comparing heights or distances in metric units, or filling out forms that ask for measurements in meters. Home improvement projects sometimes require metric measurements if you are ordering materials from international suppliers. Travel planning may involve converting distances — a hiking trail listed as 2 miles might be easier to picture if you know it is roughly 3.2 kilometers, which breaks down to 3,200 meters.

Fitness and health contexts also use meters: running track distances, swimming pool lengths, and medical measurements often appear in metric units. If you are tracking your own measurements or comparing them to standards, knowing how to convert feet helps you understand the numbers.

Why the conversion factor is 0.3048

The foot and the meter come from different measurement systems. The foot is part of the imperial system (used mainly in the United States), while the meter is the base unit of the metric system used almost everywhere else. In 1959, the international yard and pound agreement officially defined one foot as exactly 0.3048 meters. This number is not rounded — it is the legal definition, so it never changes.

Because the conversion is defined precisely, your answer will always be exact when you use 0.3048, not an approximation. If you use 0.3 for speed, you are trading accuracy for convenience.

Frequently Asked Questions

How many meters is 5 feet 10 inches?

First convert the inches to feet: 10 inches divided by 12 is 0.833 feet. Add that to 5 feet to get 5.833 feet. Then multiply by 0.3048 to get 1.778 meters. For height, people often round to two decimal places, so 5 feet 10 inches is about 1.78 meters.

Is there a difference between feet and foot when converting?

No. "Foot" is the singular form and "feet" is the plural, but the conversion factor is the same for both. One foot equals 0.3048 meters, and 100 feet equals 30.48 meters. The unit itself does not change.

What if I need to convert square feet to square meters?

Square feet and square meters measure area, not length. To convert, multiply square feet by 0.092903 (not 0.3048). So 100 square feet equals about 9.29 square meters. The conversion factor is different because you are dealing with area, not distance.

Can I round 0.3048 to 0.3 for official measurements?

No. For official documents, building codes, or any situation where precision matters, use the full 0.3048. Rounding to 0.3 introduces error that can add up if you are converting many measurements or if small differences matter. Use the shortcut only for rough estimates.

Do I need to memorize the conversion factor?

No. Write it down, bookmark a converter, or save it in your phone notes. You do not need to memorize 0.3048 — you just need to know where to find it when you need it.
