Feet to Meters Converter

Overview

How to use this calculator

1. Enter the length in feet, including decimals for partial feet (for example, 10.5 ft).
2. The calculator multiplies your input by 0.3048 to convert to meters.
3. Review the result in meters and, if needed, round or format it to match your drawings, specs, or documents.
4. If you are working from feet‑and‑inches measurements, convert inches to a decimal portion of a foot before entering the value.

Inputs explained

Feet

The length in feet you want to convert to meters. You can enter whole feet or decimal feet. To convert a feet‑and‑inches measurement, first convert the inches to a decimal (for example, 10 ft 6 in = 10.5 ft).

Outputs explained

Meters

The converted length in meters using the exact 1 ft = 0.3048 m relationship. You can round this to the number of decimal places appropriate for your project.

When to use it

• Converting construction measurements in feet to metric dimensions for use on international drawings or in CAD tools that expect meters.
• Translating US hiking distances, room dimensions, or furniture sizes into meters for travel, moving, or interior design.
• Checking metric specs when ordering parts, equipment, or building materials from manufacturers who list sizes in meters.
• Helping students and professionals move quickly between unit systems when studying physics, engineering, or architecture.
• Converting sports field dimensions, pool lengths, or trail distances into meters for international events or specifications.
• Preparing reports or documentation that require metric units even when the original measurements were taken in feet.
• Estimating elevation gains or clearances from US sources and translating them into meters for global audiences.
• Converting stage or event layouts for venues that require metric drawings and safety clearances.
• Standardizing product dimensions in metric for international ecommerce listings or catalogs.
• Translating building code minimums listed in meters for a local plan set drafted in feet.

Tips & cautions

• For feet‑and‑inches values, convert inches to decimal feet before entering (e.g., 10'6" ≈ 10.5 ft, 5'9" ≈ 5.75 ft).
• Keep an extra decimal place or two when working through design calculations, then round to a cleaner number on final drawings.
• Use the companion meters‑to‑feet converter to double‑check that your round‑trip conversions stay within acceptable tolerance.
• If you are working with very small or very large measurements, consider whether centimeters, millimeters, or kilometers might be more intuitive metric units.
• When collaborating across borders or disciplines, agree on both the primary unit system and the number of decimals everyone will use so converted numbers stay consistent.
• For quick mental checks, remember that 3 ft ≈ 0.91 m and 10 ft ≈ 3.05 m; the calculator will give the precise results when you are ready to commit to a number.
• If you need centimeters, multiply meters by 100 after conversion; for millimeters, multiply by 1,000.
• When working with tolerance stacks, keep more decimals during intermediate steps and only round at the end of the calculation chain.
• If you’re comparing products, convert all dimensions to meters first so you can compare like‑for‑like in a single unit system.
• For on‑site work, write both feet and meters on your cut list to reduce mistakes when switching between tools.
• Round only after the conversion so small errors don’t compound.
• Always verify the unit labels.
• Displays rounded decimal meters by default; you may need to adjust rounding for high‑precision engineering work.
• Does not accept feet and inches as separate inputs—you must combine them into a decimal foot value first.
• Assumes non‑negative lengths; negative values and directional conventions are not modeled.
• Focuses purely on unit conversion and does not validate whether specific tolerances, code requirements, or safety factors are satisfied for your project—those checks still require professional judgment and standards review.
• Uses the international foot definition; legacy U.S. survey foot conversions require a slightly different factor and are not covered here.

• Converts feet to meters by multiplying the input by 0.3048.
• Accepts decimal feet for partial‑foot measurements.
• Performs calculations at full precision and rounds only for display.
• Does not apply the U.S. survey foot conversion factor.

FAQs

Is this converter accurate enough for engineering and construction work?

Yes. It uses the exact definition 1 ft = 0.3048 m and retains more precision internally than is typically displayed. You should still round the result to match the level of precision required by your project, drawings, or standards.

How do I handle feet and inches with this calculator?

Convert your feet‑and‑inches measurement to decimal feet before entering it. For example, 5 ft 9 in is 5 + 9/12 ≈ 5.75 ft, and 10 ft 6 in is 10.5 ft. Enter that decimal value into the Feet field to get meters.

Can I convert meters back to feet?

Yes. Use the companion meters‑to‑feet calculator for the reverse conversion. You can also use both together as a round‑trip check when measurements are critical.

Why does my CAD or BIM software show a slightly different rounded value?

Different tools round to different numbers of decimal places or use specific display rules. The underlying conversion factor is the same, but you may see small differences depending on rounding. Align your rounding settings with the tools used on your project.

Does this handle negative values or directional distances?

The calculator is designed for non‑negative lengths only. If you need directional or signed distances, convert the magnitude and apply the sign or direction within your own coordinate or drawing system.

Does this use the international foot or U.S. survey foot?

It uses the international foot, defined as exactly 0.3048 meters. The U.S. survey foot is a legacy unit with a tiny difference and is not used here.

Why might a surveying map show a slightly different conversion?

Some legacy geodetic datasets used the U.S. survey foot. The difference is small but can matter over long distances. Confirm which foot definition your dataset requires before converting.

What if my starting measurement is in yards or miles instead of feet?

You can still use this tool by doing a quick pre‑conversion. For yards, multiply by 3 to get feet (for example, 12 yd = 36 ft) and then enter that value. For miles, multiply by 5,280 to get feet before converting. If you work with these units often, consider pairing this calculator with a yards‑to‑meters or miles‑to‑kilometers reference chart in your workflow.

Can I convert directly to centimeters or millimeters?

Yes. Once you have meters from this calculator, multiply by 100 to get centimeters or 1,000 to get millimeters. For example, 2.4 m = 240 cm = 2,400 mm. Keeping everything in meters during design and only converting to smaller units when documenting final dimensions can reduce rounding errors in complex projects.
