Does cAdvisor use binary or decimal system when reporting bytes

Question

I am using cAdvisor v0.44.0 to expose container metrics which are collected by Prometheus and visualized in Grafana. One of the cAdvisor metrics is container_network_receive_bytes_total. Let's say that its value is 554325454. Should bytes reported by cAdvisor be converted to MB with decimal or binary approach?

1. 554325454 bytes = 554.3254539999999 MB (decimal)
2. 554325454 bytes = 528.6459484100342 MB (binary)
