Feet to Meters Calculator

Direct answer

Multiply the entered feet value by 0.3048 to express it in meters (m). This converts foot (ft) to meter (m) within the documented length family.

Variables and formula

• Feet (ft): the source value measured in foot.
• Meters (m): the same quantity expressed in meter.
• Conversion factor: 0.3048 meters per foot.

Meters = Feet × 0.3048

The generator emits numeric factors with at most 15 significant digits. Calculator results keep up to 10 significant digits for display; this formatting does not increase the precision of the measurement.

Unit definitions and named variants

Source unit: foot (ft). This foot is the international foot, defined as exactly 0.3048 meter. Named variant used: International foot; the U.S. survey foot (1200/3937 m) is a distinct legacy unit. Reference: National Institute of Standards and Technology: NIST Handbook 44 (2026), Appendix C: General Tables of Units of Measurement.

Target unit: meter (m). The meter is the U.S. English spelling of the metre, the SI base unit of length, defined through the fixed numerical value of the speed of light in vacuum. The canonical meter definition is used; no alternate named variant is implied. Reference: Bureau International des Poids et Mesures: The International System of Units (SI), 9th edition, version 4.01.

The ft-to-m direction remains inside the length quantity; it changes the unit label and numerical scale, not the kind of quantity being measured.

Relationship and precision

The named unit relationships are defined or exact, so the conversion is exact before display rounding and source-measurement uncertainty.

• ft relationship: The terminating base factor is exact.
• m relationship: The base factor is exactly 1 by the family base-unit choice.

To audit the factor through the family base unit, divide the raw dataset factors 0.3048 by 1. The generator emits that quotient once at 15 significant digits as the canonical direct factor 0.3048; runtime calculations do not divide the already-emitted base factors again.

Reproducible example

For 10 feet, 10 × 0.3048 = 3.048 meters. Repeating the same multiplication with the stated factor reproduces the displayed conversion before interface rounding.

Directional scale check

Because one foot contains 0.3048 meters, the target number is smaller than the source number for every positive input. Zero maps to zero, while negative inputs are rejected because this family models non-negative magnitudes.

Interpretation

Read the result as meters, not feet. A value entered as ft leaves the calculator labelled m; this directional distinction matters even when the two units describe the same length quantity.

Assumptions and limitations

• Only non-negative length magnitudes are accepted by this family.
• A conversion does not add significant figures to the source measurement.
• This family converts non-negative length magnitudes; it does not infer direction, path, displacement, or measurement uncertainty.

Common mistakes

• Do not apply this factor to legacy data explicitly labelled U.S. survey foot.
• Do not confuse the unit symbol m with the SI prefix milli (m).

Continue within the Length family

See the Length conversion hub for its five-unit reference table and all 20 directed routes.

• Reverse the direction: Meters to Feet
• Compare another length route: Feet to Kilometers
• Compare another length route: Feet to Centimeters
• Compare another length route: Feet to Miles
• Compare another length route: Meters to Kilometers

Assumptions

• The entered value uses feet exactly as labelled.
• Only non-negative length magnitudes are accepted by this family.
• Rounding and measurement uncertainty remain the user's responsibility.
