//! `units` — domain-agnostic oilfield-unit conversion constants and helpers.
//!
//! One home for every unit factor so downstream consumers can never disagree on
//! a conversion. Pure arithmetic over `f64` — no I/O, no domain types, no error
//! surface. Curated here (rather than a consumer's own module) so the whole
//! family shares one set of constants; moved out of petekSim's `srs-units`.
//!
//! ```
//! use petektools::units::{acres_to_ft2, ACRE_TO_FT2};
//! assert_eq!(acres_to_ft2(2.0), 2.0 * ACRE_TO_FT2);
//! ```
