There is no conversion from hp to mph.
Horsepower (hp) and miles per hour (mph) are not directly convertible since they measure different things: power and speed, respectively. The speed a vehicle can achieve with 300 hp depends on various factors, including the vehicle's weight, aerodynamics, drivetrain efficiency, and gearing. For example, a well-designed sports car with 300 hp might reach speeds of 150 mph or more, while a heavier vehicle may achieve lower speeds. Thus, the mph achievable with 300 hp varies widely based on the specific vehicle and conditions.
The relationship between horsepower (hp) and speed (mph) depends on several factors, including the weight of the vehicle, the efficiency of the powertrain, and the type of terrain. Generally, a rough estimate is that 1 horsepower can propel a vehicle at about 15 mph under ideal conditions. Therefore, 10 hp could potentially translate to speeds around 150 mph, but this is highly theoretical and actual speeds would be influenced by many variables.
A category 4 hurricane has sustained winds of 130 to 156 mph.
The horsepower (hp) rating of a washing machine motor can vary depending on its size and design, but typically ranges from 1/4 hp to 1/2 hp. Smaller household washing machines may have motors closer to 1/4 hp, while larger or more heavy-duty models may have motors closer to 1/2 hp.
4 knots is equivalent to approximately 4.6 miles per hour.

The very first Spitfire flew at around 345 mph, but that was with a Merlin 'C' of 1,045 hp and a 2 blade prop. By mid-war they were flying at over 435 mph with 1.700 hp Merlins with 4 and 5 blade props.
