Unit

How this is generated

Source: lib/opsinjs.ts. Script: scripts/build-reference.mts. Command: pnpm run generate.

Everything below is copied from the symbol, so a page is improved by improving its doc comment. The API index says why there is a page per symbol and what these pages still do not carry.

Unit

One unit: what it is called, what a reader sees, and how it is SPOKEN.

The spoken form is the whole reason this table exists. A screen reader handed mmHg improvises a pronunciation, and "one twenty over eighty em em aitch gee" is a failure rather than a quirk.

There is no reference range here, no threshold, no plausibility bound and no default precision. A unit table says what a number is measured in; it never says what a number should be. Decimal places belong to the MEASUREMENT and travel with it from the product - health/numbers-units-precision, rule 2.

joined is typography, not a claim about a reading: it records that a symbol sits against the number with no space, as everyday English writes 98% and 36.8°C. Which symbols take it is settled by content/docs/content/grammar-and-mechanics.mdx, not by this table.
