What are micros in Google Ads?

The cost metrics are provided as micros by the Google Ads API. This means a returned value for "cost_micros" of 5,000,000 equals 5 (once divided by 1,000,000).

In order to avoid micros we suggest to subdivide all micros by 1,000,000 by using the operator math.div(variable,1000000).

An explanation how to use operators can be found in the knowledge base.
