To convert 100 foot to mile, divide 100 by the number of feet in a mile (5280). Alternatively, multiply 100 by the conversion factor 0.000189. So, 100 foot ÷ 5280 foot/mile = 0.0189 mile.

100 foot equals exactly 0.01893939... mile. For most practical purposes and quick reference, this is often rounded to 0.0189 mile.

Objects measuring approximately 100 foot include a 100-foot section of a standard American football field (excluding end zones), the approximate height of a small cellular communication tower, or a 100-foot heavy-duty extension cord.

Converting foot to mile is useful for expressing shorter distances within a larger context, such as surveying property boundaries, planning short segments of infrastructure projects, or understanding distances in aviation or navigation where miles are the standard unit for longer distances.

A simple memory aid is to remember that 100 feet is roughly one-fiftieth of a mile (1/50 = 0.02). Visualize 100 feet as a very short segment of a road, much smaller than a full mile, to grasp the scale.
