What does one watt [W] represent?

One watt is the SI derived unit of power, equal to one joule of energy transferred per second, measuring the rate of work or energy transfer.

What is water horsepower used for?

Water horsepower measures the theoretical mechanical power related to moving water, commonly used for sizing pumps and evaluating hydraulic systems.

Is the conversion from watt to horsepower (water) exact in all cases?

No, it is a theoretical conversion assuming ideal conditions; actual pump performance and fluid dynamics can cause differences.
