Conversion Formula
The conversion from feet to metres is based on the formula: metres = feet × 0.3048. Since one foot equals exactly 0.3048 metres, multiplying the number of feet by this factor gives the length in metres. For example, 90 feet: 90 × 0.3048 = 27.432 metres.
This formula works because it is a direct proportional relationship between the two units, allowing for accurate conversion by simple multiplication. It ensures consistency across measurements and is standardized internationally.
Conversion Example
- Convert 50 feet to metres:
- Multiply 50 by 0.3048.
- 50 × 0.3048 = 15.24 metres.
- Convert 120 feet to metres:
- Multiply 120 by 0.3048.
- 120 × 0.3048 = 36.576 metres.
- Convert 200 feet to metres:
- Multiply 200 by 0.3048.
- 200 × 0.3048 = 60.96 metres.
- Convert 75 feet to metres:
- Multiply 75 by 0.3048.
- 75 × 0.3048 = 22.86 metres.
- Convert 10 feet to metres:
