If you are using the InfluxQL language (and not the new Flux language), then math between fields in a measurement is possible:

There is no support for cross-measurement or sub queries for InfluxQL. It is possible with Flux: https://davidgs.com/2019/using-cross-measurement-math-in-influxdb-flux/ and https://www.influxdata.com/blog/influxdb-how-to-do-joins-math-across-measurements/
