When describing visibility, what measurement could potentially be used?

Visibility in meteorology is typically expressed in statute miles, but fractions can also be used to represent visibility in conditions where measurements are less than a full mile. In this context, 1/2 is a common measurement used to describe visibility.

This fraction indicates that visibility is limited to half a mile, which is a situation often encountered in fog, heavy rain, or other atmospheric phenomena that obscure sight lines. The choice of 1/2 is well understood and widely used in weather reporting.

The other measurements, while they represent fractional distances, are less standard in practical meteorological reporting. For instance, visibility of 3/16 or 1/3 is not typically applicable in standard reports. In many regulations and practices, visibility values are rounded to the nearest quarter or half mile for clarity and consistency, making 1/2 a more recognizable and applicable choice in various weather conditions.
