About these units
Foot/Hour (ft/h)
A foot per hour is almost comically slow, yet still relevant in specific technical fields. Pipeline corrosion creep, structural deformation, glacial shifts, and certain chemical processes may be measured in ft/h when imperial units are required. While practically invisible to human perception, speeds expressed in ft/h become meaningful over long intervals, providing insight into incremental natural or mechanical change.
Knot (UK) (kt (UK))
The UK knot historically varied slightly from the international knot because the UK used different values for the nautical mile depending on era and maritime authority. Though the differences were minor, they mattered in navigation, where precision affects charting, dead reckoning, and ocean voyaging. Modern UK practice fully aligns with the international knot (1 nautical mile per hour), but historical documents and charts may reference older UK knot values. The knot's rich maritime heritage—used by sailors measuring speed with knotted ropes dragged along the water—makes it one of the oldest continuously used speed units.
