Convert measurements within a system and use unit reasoning to choose the correct scale.
Convert to a larger unit
Problem
Convert \(48~\text{inches}\) to feet.
Big Picture
What this problem is really about
Think of the conversion as grouping smaller units into larger ones. Arrange the unit ratio so the original unit cancels and the requested larger unit remains, which is equivalent to dividing by the number of small units per large unit. The result should have a smaller numerical measure because each new unit covers more length.
