Celsius to Fahrenheit conversion

How to I convert from Celsius to fahrenheit.

SELECT mean(“value”) FROM “autogen”.“ipmi_sensor” WHERE (“server” = ‘192.168.20.15’ AND “unit” = ‘degrees_c’) AND timeFilter GROUP BY time(__interval) fill(null)

SELECT mean(“value”) * 0.018 + 32 FROM “autogen”.“ipmi_sensor” WHERE (“server” = ‘192.168.20.15’ AND “unit” = ‘degrees_c’) AND timeFilter GROUP BY time(__interval) fill(null)
