📖 About Ft to M

Distance Metrology & NIST SP 811 Standards

Under the International Yard and Pound Agreement of 1959, 1 international foot is defined as exactly 0.3048 meters (304.8 mm).

Primary Length Multipliers

  • 1 Foot (ft): 0.3048 Meters = 30.48 cm = 12 in = (1) / (3) yd
  • 1 Meter (m): = (1) / (0.3048) ft ≈ 3.280839895 Feet = 39.3700787 Inches
  • Feet to Meters Formula: Meters = Feet × 0.3048
  • Meters to Feet Formula: Feet = Meters0.3048

How to Use This Calculator

Enter your Length / Distance to Convert (e.g. 100.0) and Conversion Direction — choose from Feet to Meters (ft → m / multiply by 0.3048), Meters to Feet (m → ft / divide by 0.3048). Results update instantly as you type — adjust any value to compare scenarios.

Worked Example

Understanding Your Result

Unit conversion precision: round to the same number of significant figures as your original measurement. Converting 6 feet to meters gives 1.8288 m — but if your measurement was approximate (±1 inch), expressing more than 2 decimal places is false precision. For international trade and technical specifications, SI units (meters, kilograms, liters) are the standard. US customary units (feet, pounds, gallons) differ from Imperial UK units: 1 US gallon = 3.785 L vs. 1 UK gallon = 4.546 L.

❓ Frequently Asked Questions

How many meters are in 1 foot?

There are exactly 0.3048 meters in 1 international foot.

How many feet are in 1 meter?

There are approximately 3.28084 feet in 1 meter.

How do you convert 100 feet to meters?

Multiply 100 by 0.3048 to get exactly 30.48 meters.

What is an easy way to estimate feet to meters?

Divide the number of feet by 3 and subtract roughly 10% (e.g., 100 ft ÷ 3 ≈ 33.3 - 3.3 ≈ 30 m; the exact value is 30.48 m).

Why do aircraft measure altitude in feet rather than meters?

The International Civil Aviation Organization (ICAO) standardizes altitude in feet (Flight Levels) across most of global airspace for safe vertical separation (1,000-foot increments).
