The furlong–firkin–fortnight (FFF) system is a humorous system of units based on unusual or impractical measurements. The length unit of the system is the furlong , the mass unit is the mass of a firkin of water, and the time unit is the fortnight .
1 nautical mile per hour (by definition), 1 852.000 metres per hour (exactly), [5] 0.51444 metres per second (approximately), 1.15078 miles per hour (approximately), 20.25372 inches per second (approximately) 1.68781 feet per second (approximately). The length of the internationally agreed nautical mile is 1 852 m.

A basic airspeed indicator with the indicated airspeed (IAS) indicated in knots ("Kt" or "Kts" or "KIAS") -- the most common unit of measure for airspeed. Some airspeed indicators in aircraft prior to the mid-1970s indicate in miles per hour plus knots (1 knot = 1.15 mph) or kilometers per hour (1 knot = 1.85 km/h).
One form of the Darcy–Weisbach equation for fluid flow is =, where ΔP is the pressure drop, ρ is the mass density, f is the (dimensionless) friction factor, L is the length of the pipe, Q is the volumetric flow rate, and d is the pipe diameter. It might be desirable to have the equation in the form
Two knots can be added by cutting both knots and joining the pairs of ends. The operation is called the knot sum , or sometimes the connected sum or composition of two knots. This can be formally defined as follows ( Adams 2004 ): consider a planar projection of each knot and suppose these projections are disjoint.
