# Units on every metric

September 2026 · API

Most metrics now declare their unit in the API catalog and in the definition record, and units_source says where each unit came from.

## What's new

Newhedge now declares the unit for most metrics in the API catalog and in the definition record.

`units_source` says where each unit came from: `declared` when Newhedge states the unit, `chart` when it is the unit the metric's own chart already shows beside the value, and `heuristic` when it was inferred from the metric name. A metric whose unit is not established publishes `units: null` rather than a guess.

## Methodology

Ratio metrics such as the AVIV ratio, the put/call ratio, and SOPR are no longer labelled as percentages.

The vague `count` and `rate` labels are gone. Those metrics now name what they count, such as blocks, transactions, or addresses.
