How to convert data in KByte/s imported from InfluxDB to Kbit/s in graph axe?

Hi all,
We use influxDB and import data in it from switches. These datas are on KBytes/s.
In Grafana, we want to convert these datas in Kbit/s before displaying.
How we can do that ? How to multiply by 8 in Metrics ?
Thanks in advance for your response.
Best regards,

Use math expression in query and multiply by 8

Thanks for your response !
