Confused over ore-to-plates ratio
Re: Confused over ore-to-plates ratio. by astroshak » Sun Sep 12, 2021 7:23 pm. 15/30/45 items/sec, or 900/1800/2700 items/min. Most people use items/sec, by the way, unless talking science, which is talked about per minute. For Steel Furnaces (craft speed 2) you need 24/48/72 furnaces to turn a full belt of ore into a full belt of plate.
