15 Ft to Metres – Full Calculation Guide

Conversion result: 15 feet equals approximately 4.572 metres.

Since 1 foot equals 0.3048 metres, multiplying 15 by this factor gives the length in metres. This calculation helps to convert measurements from feet to metres, useful in various contexts like construction, science, or travel where metric units are standard.

Conversion Calculation

To convert feet to metres, the formula used is: metres = feet × 0.3048. This works because the metre is a metric unit based on the international definition, and feet are imperial units. For example, for 15 ft: 15 × 0.3048 = 4.572 metres, ensuring precise measurement translation.

Conversion Formula

The formula to convert feet into metres is: metres = feet × 0.3048. This works because the metre is defined as exactly 1.000027 yards or 39.37 inches, and 1 foot equals 12 inches. So, multiplying feet by 0.3048 converts the length into the metric system, which is based on decimal units.

For example, converting 10 ft: 10 × 0.3048 = 3.048 metres. The process involves multiplying the number of feet by the conversion factor, ensuring an accurate translation from imperial to metric units, which is essential for scientific and international measurements.

Conversion Example

  • Convert 20 ft to metres:
    • Multiply 20 by 0.3048
    • 20 × 0.3048 = 6.096 metres
    • This shows 20 feet equals 6.096 metres.
  • Convert 5 ft to metres:
    • Multiply 5 by 0.3048
    • 5 × 0.3048 = 1.524 metres
    • This means 5 feet is 1.524 metres long.
  • Convert 25 ft to metres:
    • Multiply 25 by 0.3048
    • 25 × 0.3048 = 7.62 metres
    • So, 25 feet equals 7.62 metres.
  • Convert 8 ft to metres:
    • Multiply 8 by 0.3048
    • 8 × 0.3048 = 2.4384 metres
    • Therefore, 8 feet is 2.4384 metres.
