Work out knots converter instantly with clear inputs, formula shown and shareable results.
Each speed unit is defined as a multiple of the metre per second, so the conversion runs in two steps: multiply by the source unit's factor to reach metre per second, then divide by the target unit's factor. One factor per unit covers every pair in the list. A knot is one nautical mile per hour, and the nautical mile is exactly 1,852 m, so 1 kn = 1.852 km/h exactly.
Two-step conversion
result = value × factor(from) ÷ factor(to)
Base value
base (metre per second) = value × factor(from)
With 5 units, direct pairs would mean 20 factors to maintain. Going via metre per second needs one factor per unit and gives the same answer.
Yes. The first is the unit your figure is already in; the second is what you want it in. Swapping them inverts the result.
