What is the default precision for inserting data into InfluxDB?

nanoseconds
Timestamp precision When writing data to InfluxDB, we recommend including a timestamp with each point. If a data point does not include a timestamp when it is received by the database, InfluxDB uses the current system time (UTC) of its host machine. The default precision for timestamps is in nanoseconds.

Where is InfluxDB data stored?
