Martin Desruisseaux created SIS-378: ---------------------------------------
Summary: Too aggressive simplification of some units of measurement Key: SIS-378 URL: https://issues.apache.org/jira/browse/SIS-378 Project: Spatial Information Systems Issue Type: Bug Components: Utilities Affects Versions: 0.8 Reporter: Martin Desruisseaux In the left column, some units used by the World Meteorological Organisation (WMO). In the right column, the result of parsing with Apache SIS. Some simplifications are too aggressive, in particular with dimensionless units like radians. || WMO units || After SIS parsing || Ok || | K m2 kg-1 s-1 | K⋅m²∕(kg⋅s) | (/) | | m m6 m-3 | m⁴ | (!) | | Pa s-1 | kg∕(m⋅s³) | (!) | | S m-1 | A²⋅s³∕(kg⋅m³) | (!) | | kg kg-1 m s-1 | m∕s | (!) | | m2/3 s-1 | 0.3333333333333333⋅m²∕s | (x) | | J kg-1 | m²∕s² | (!) | | mol mol-1 | | (!) | | mol s-1 | mol∕s | (/) | | K s-1 | K∕s | (/) | | m s-1 | m∕s | (/) | | m s-2 | m∕s² | (/) | | Pa m | kg∕s² | (!) | | m3 s-1 | m³∕s | (/) | | kg m-2 s-1 | kg∕(m²⋅s) | (/) | | μg m-3 | 1.0E-9⋅kg∕m³ | (!) | | K m-1 | K∕m | (/) | | W m-2 | kg∕s³ | (!) | | N m-2 | Pa | (?) | | (m2 s sr)-1 | -1⋅m²⋅s | (x) | | kg m-2 | kg∕m² | (/) | | kg m-3 | kg∕m³ | (/) | | K*m s-1 | K⋅m∕s | (/) | | cm/day | 1.1574074074074074E-7⋅m∕s | (!) | | m-2 s rad-1 | s∕m² | (x) | | N m-2 s | kg∕(m⋅s) | (!) | | kg kg-1 s-1 | Hz | (x) | | kg/kg*kg/kg | | (!) | | K*m/s | K⋅m∕s | (/) | | kg/kg*Pa/s | kg∕(m⋅s³) | (!) | | kg/kg*m/s | m∕s | (!) | | day | d | (/) | | µg m-3 | 1.0E-9⋅kg∕m³ | (!) | | Pa*Pa | kg²∕(m²⋅s⁴) | (!) | | W m-2 Hz-1 | kg∕s² | (!) | | W sr-1 m-2 | kg∕s³ | (x) | | N m-1 | kg∕s² | (!) | | W m-1 sr-1 | kg⋅m∕s³ | (x) | | m-2 s-1 | ∕(m²⋅s) | (!) | | ° | ° | (/) | | kg kg-1 | | (!) | | s m-1 | s∕m | (/) | | W m-3 sr-1 | kg∕(m⋅s³) | (x) | | K*Pa/s | K⋅kg∕(m⋅s³) | (!) | | m3 m-3 | | (!) | | V m-1 | kg⋅m∕(s³⋅A) | (!) | | m2 s-2 | m²∕s² | (/) | | m2 s-1 | m²∕s | (/) | | mol m-3 | mol∕m³ | (/) | | psu | psu | (/) | | J m-2 | kg∕s² | (!) | | kg-2 s-1 | ∕(kg²⋅s) | (!) | | K*K | K² | (/) | | kg m-3 s-1 | kg∕(m³⋅s) | (/) | | m3 s-1 m-1 | m²∕s | (!) | |(kg m-3) (m s-1) | kg∕(m²⋅s) | (!) | | W m-2 nm-1 | 9.999999999999999E8⋅kg∕(m⋅s³) | (!) | -- This message was sent by Atlassian JIRA (v6.4.14#64029)
