Shaft horsepower (HP) is the traditional unit used to describe the power output of marine propulsion systems. It represents the mechanical power delivered to the propeller shaft and is still widely referenced in ship specifications and engine catalogs.
In the metric system, the kilowatt (kW) is the standard unit of power, defined as one thousand joules per second. Converting HP to kW allows engineers to compare marine engines with other mechanical and electrical systems that use SI units.
The metric horsepower, or cheval‑vapeur (CV), is another historic unit used mainly in Europe. Although similar to HP, CV is slightly smaller (1 CV ≈ 0.7355 kW). Understanding the relationship among HP, kW, and CV is essential for accurate performance calculations and fuel‑consumption estimates.
