Which unit conversion is correct for converting feet to meters?

The correct conversion for converting feet to meters is based on the precise relationship established in the metric system. One foot corresponds to exactly 0.3048 meters. This conversion is derived from the defined length of a meter in relation to the foot, ensuring accuracy in measurements and applications across various fields, including engineering, architecture, and geography.

The other options demonstrate inaccuracies based on the actual measurement equivalencies. For instance, stating that one foot equals 0.5 meters or 1.5 meters does not align with the established metric conversion, as it exaggerates or diminishes the true measure. Similarly, claiming that one foot equals 1 meter misrepresents the size difference considerably. Hence, the ratio of 1 foot to 0.3048 meters is widely utilized for accurate conversions in GIS applications and other scientific domains.
