Knot (UK) to Yard per Hour

The UK knot is a historical variation of the knot based on the British nautical mile (6,080 feet) rather than the international nautical mile (6,076.12 feet).

1 UK knot ≈ 1.853184 km/h = 0.5148 m/s. Slightly faster than the international knot (1.852 km/h).

To international knots: × 1.00064. To km/h: × 1.853. To m/s: × 0.5148.

None in modern use. Only relevant for interpreting historical British naval records.

The difference between UK and international knots is only 0.064% — barely noticeable but important for precise navigation.

Assuming all old British ship logs use the same knot as today — they don't, but the difference is tiny.

Historical only. Effectively identical to modern knot. Only matters for historical maritime research.

Yard per hour measures distance in yards traveled over one hour. Rarely used except in specialized contexts.

1 yd/h = 0.000254 m/s = 0.0009144 km/h = 0.9144 m/h.

To yd/min: ÷ 60. To ft/h: × 3. To m/h: × 0.9144.

No common modern applications. Might appear in some historical documents.

No notable facts — too rarely used.

Even existing is a mistake — use m/h, ft/h, or mph instead.

1,760 yd/h = 1 mph. Extremely uncommon. Better to use other units.
