VOUnit 1.1 Proposed Recommendation: Request for Comments

VOUnit proposes a recommended syntax for writing the string representation of unit labels.

Latest version of VOUnits can be found at:

Reference Interoperable Implementations

  • DaCHS 2.8. To try things out, you could run, with DaCHS installed, run python -c 'from gavo.base import unitconv;print(unitconv.computeConversionFactor("pc/yr", "m/s"))' or the like

  • Unity library (canonical home page https://purl.org/nxg/dist/unity): Parsing library for the VOUnits syntax, as well as for the FITS, OGIP and CDS syntaxes. There are parser implementations in Java and C. As well, this project produces formal (yacc-style) grammars for the syntaxes it supports.

Implementations Validators

Both implementations serve as validators. In the DaCHS case, you could run python -c "from gavo import api;print(api.parseUnit('kg/(m.s**2)'))".
