What Is The Bitrate Measurement?

I’m making tweaks to the bitrate in the TCPUtils file: lib-jitsi-meet/TPCUtils.js at master · jitsi/lib-jitsi-meet · GitHub

const DESKTOP_SHARE_RATE = 500000;
const LD_BITRATE = 200000;
const SD_BITRATE = 700000;
const HD_BITRATE = 2500000;

Are these kbps, mgbps, or something else?

bps / bits per second
