Zigbee2MQTT Location/ Temp Setting

I recently installed the Sonoff Zigbee dongle with Zigbee2MQTT. On the Zigbee2MQTT frontend, there is no option to set the location to USA. I have seen the US location set in screenshots of the Zigbee page of forums but I’m not sure how to set it. Also, is there a way to change the temp format from C to F?
