Meter per Hour to Knot (UK)

Meter per hour measures the distance in meters traveled over the course of one hour. It's a very slow speed unit used for measuring gradual processes.

1 m/h = 1/3600 m/s = 0.000278 m/s. Very small speed unit for very slow processes.

To m/s: ÷ 3,600. To km/h: ÷ 1,000. To ft/h: × 3.281.

Glacier movement (typically 10–200 m/h in fast glaciers), hair growth (0.0001 m/h), slow industrial processes, and scientific experiments.

Average glacier: 10–100 m/h. Tectonic plate movement: ~0.005 m/h. Bamboo (fastest growing plant): up to 0.091 m/h.

Confusing m/h with m/s — m/h is 3,600 times slower. Using it for normal speeds instead of km/h or m/s.

Remember: 1,000 m/h = 1 km/h. Useful for very slow processes. Think glaciers, not cars.

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.
