The basic conversion: multiply feet by 0.3048
To convert feet to meters, multiply the number of feet by 0.3048. This is the fixed conversion rate — one foot equals exactly 0.3048 meters. So 10 feet equals 3.048 meters, and 100 feet equals 30.48 meters.
The math is straightforward because the conversion factor never changes. Unlike currency or measurements that vary by region, the foot-to-meter relationship is constant worldwide. You can use a calculator, a spreadsheet, or do it by hand — the answer will be the same.
If you need to go the other direction (meters to feet), divide the number of meters by 0.3048, or multiply by 3.28084. Most people find it easier to remember the feet-to-meters direction since that's the more common conversion in everyday life.
Key Takeaways
- Multiply any number of feet by 0.3048 to get the measurement in meters.
- One foot equals exactly 0.3048 meters — this ratio never changes.
- For rough estimates, remember that one meter is about 3.3 feet, so divide feet by 3 to get close to meters.
- Online converters and phone calculator apps can do the math instantly if you don't want to multiply by hand.
- Rounding to two decimal places is usually precise enough for home, construction, and travel purposes.
When you'll encounter this conversion at home
Homeowners and renters run into feet-to-meters conversions most often when dealing with international measurements. If you're buying furniture, appliances, or building materials from overseas sellers, dimensions often come in meters. Ceiling height, room width, and doorway clearance are common examples — knowing how to convert helps you confirm that a piece will actually fit.
Contractors and inspectors sometimes use metric measurements too, especially if they trained abroad or work on commercial projects. If someone tells you a wall is 3.5 meters tall and you're thinking in feet, the conversion takes seconds. It also prevents expensive mistakes — ordering the wrong size item or misunderstanding a room's actual dimensions.
Quick reference for common household measurements
Here are conversions for sizes you'll see regularly:
| Feet | Meters | Common use |
|---|---|---|
| 3 | 0.91 | Standard doorway height |
| 6 | 1.83 | Typical ceiling height |
| 8 | 2.44 | Taller ceiling or wall height |
| 10 | 3.05 | Room width or length |
| 20 | 6.10 | Lot depth or large room |
You can use this table as a starting point, but for any measurement that matters — like confirming a piece of furniture will fit through a doorway — do the full calculation rather than rounding from the table.
Using online tools and calculators
If math isn't your preference, dozens of free online converters do this instantly. Type the number of feet into any search engine along with "feet to meters" and a calculator appears at the top of the results. Your phone's built-in calculator app usually has a unit converter too — open it, look for the converter icon, and select length or distance.
Spreadsheet programs like Excel and Google Sheets can also do the conversion. In Google Sheets, you can use the formula =CONVERT(10,"ft","m") to convert 10 feet to meters. This is useful if you're working with a long list of measurements and don't want to convert each one by hand.
Why the conversion factor is 0.3048, not a rounder number
The conversion factor exists because the foot and meter come from different measurement systems. The meter is part of the metric system, defined by the distance light travels in a vacuum in a specific fraction of a second. The foot is part of the imperial system, which has historical roots in body measurements and was standardized differently.
In 1959, the United States and other countries officially agreed that one foot equals exactly 0.3048 meters. This precise number is the legal definition used worldwide, so you'll always use this same factor. It's not an approximation — it's the official conversion.
Rounding for practical purposes
For most home and construction work, you don't need extreme precision. Rounding to one or two decimal places is fine. Three feet becomes 0.91 meters (not 0.9144), and 10 feet becomes 3.05 meters (not 3.048). The difference matters only in specialized fields like engineering or surveying.
If you're checking whether furniture fits through a doorway or estimating room size, rounding to the nearest tenth of a meter is usually enough. If you're ordering custom-built items or working on structural repairs, ask the supplier or contractor what precision they need before you round.
Frequently Asked Questions
Do I need to memorize the conversion factor?
No. Write it down, bookmark a converter, or save it in your phone's notes. You'll use it occasionally, not daily, so looking it up each time is normal and faster than trying to remember.
What's a quick way to estimate without a calculator?
Divide the feet by 3 to get a rough estimate. Ten feet divided by 3 is about 3.3 meters — the actual answer is 3.05, so you're close enough for ballpark purposes. This works well for quick mental math but isn't precise enough for ordering or building.
Should I round up or down when measurements matter?
Round to the nearest value, not consistently up or down. If you're checking whether something fits, round conservatively — round up for width and down for height — so you don't accidentally order something too large or assume a space is taller than it is.
Can I convert square feet to square meters the same way?
No. For area, multiply square feet by 0.092903 to get square meters. The conversion is different because you're dealing with two dimensions, not one. A 10-by-10-foot room (100 square feet) is about 9.29 square meters, not 30.48.
What if I need to convert feet and inches together?
Convert the feet and inches separately, then add them. Five feet 6 inches is 5.5 feet (since 6 inches is half a foot), which equals 1.68 meters. Or convert 5 feet to 1.52 meters and 6 inches (0.5 feet) to 0.15 meters, then add them for 1.67 meters — the tiny difference is just rounding.
