Meter

Fundamental SI Metrology & BIPM Standards

The Meter (symbol: m) is the base unit of length in the International System of Units (SI). In 1983, the 17th CGPM defined the meter as the length of the path traveled by light in vacuum during a time interval of 1 / 299,792,458 of a second.

Primary Meter Multipliers

• 1 Meter: 3.280840 ft = 39.370079 in = 1.093613 yd = 100 cm = 1,000 mm

• 2 Meters: = 6.56 ft = 6 ft 6.7 in = 200 cm

• 3 Meters (Room Height): = 9.84 ft = 9 ft 10.1 in = 300 cm

• 10 Meters: = 32.81 ft = 10.94 yd = 1,000 cm

• 100 Meters (Sprint): = 328.08 ft = 109.36 yd = 0.10 km

• 1,000 Meters (1 km): = 3,280.84 ft = 0.6214 mi

Worked Example

A 5-meter room length measures 16 feet 4.8 inches (196.85 inches) or 5.47 yards for carpet and flooring installation.

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.
