Endpoint API: Get Network Traffic 'sent' and 'received' values

[LFull]

I'm currently developing a Python script with API endpoints, specifically get_network_traffic (https://developer.cisco.com/meraki/api/#/python/api-endpoints/networks/get-network-traffic). My only question is what unit of measure is being used for the returned 'sent' and 'received' values, KB?, GB?, MB? or does this represent the number of packets sent?

Any help with this issue would be much appreciated!

Not sure if that's going to be readable but it looks like it's reporting in KB.
