How to interpret the maximum message size of Azure Event Hubs

The Event Hubs FAQ section states that the maximum message size of the standard tier Event Hubs is 1MB.

I'd like to know if this is actually in MiB, so 1,048,576 bytes or if it's using factor 1000, so 1,000,000 bytes.

And I'd like to know if all meta information is included in that byte count or if the limit is only on the raw message content (i.e. without AMQP headers or Kafka Headers in the case we're using the Kafka API).

Thanks!
