Units and numeric conventions

Canonical units for the public API (design §8.3). ECNet.fit does not perform silent unit conversion on model targets; values are used as supplied by the caller or by bundled .target files.

Blend properties

Quantity	Canonical unit	Notes
Cloud point (blend I/O)	°C	Internal Rankine conversion remains an implementation detail; public inputs and outputs stay in °C.
Kinematic viscosity	cSt	Mixing rule follows Ding et al. as implemented in ecnet.blends.kinematic_viscosity.
Cetane number, YSI, LHV, octane numbers (RON/MON)	Dimensionless property scales	Same scales as the bundled target files; see Bundled property datasets for per-property cards and known provenance limits.

Model targets

Regression targets for ECNet follow the units of the supplied dataset. Bundled loaders return the scales stored in package data without converting temperature, viscosity, or other engineering units inside the model.
