Temperature and pressure query
editI wanted to take a look at all the statements we have for this property so far. But I still get duplicates and I don't know how to get the units in SPARQL:
SELECT ?item ?itemLabel ?value ?pressureValue ?tempValue
WHERE
{
?item wdt:P2118 ?value .
?valueStatement ps:P2118 ?any .
wd:P2077 wikibase:qualifier ?pressureQual .
?valueStatement ?pressureQual ?pressureValue .
wd:P2076 wikibase:qualifier ?tempQual .
?valueStatement ?tempQual ?tempValue .
SERVICE wikibase:label { bd:serviceParam wikibase:language "en" }
