I started using metric when I realized that, on my system, at 75% brewhouse efficiency and brewing a 6 gallon batch ( approx 23L ). I could just use the last 3 digits of the OG to calculate how many kg of grain I needed for a batch. e.g. 1.050 OG would require 5.0kg of grain I still use degrees F for temp but I am also switched over to liters for volume. The metric system makes things so much easier.
