Here's the breakdown:

* 1 knot = 1 nautical mile per hour.

* 1 nautical mile ≈ 1.1508 statute miles ≈ 1.852 kilometers.

Therefore, a knot is roughly equivalent to 1.15 miles per hour or 1.85 kilometers per hour.

It's important to note that knots are primarily used for maritime and aviation purposes because they are based on the nautical mile, which is a unit of distance used in navigation.
