About these units
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 Modern UK practice fully aligns with the international knot (1 nautical mile per hour), but historical documents and charts may reference older UK knot values.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.
Foot/Minute (ft/min)
A foot per minute is common in industrial engineering, HVAC air flow analysis, elevator design, and manufacturing processes. Ventilation rates in ducts are often reported in ft/min, making the unit crucial for designing safe and comfortable living spaces. In machining, ft/min corresponds to cutting speed along a tool edge, helping determine tool wear and material removal rates. Despite being less familiar in daily life, ft/min is a key engineering unit.
