Last sentence of 3rd paragraph states that propylene glycol has slightly better heat transfer capability than ethylene glycol. ILM 070305m v5.1 page 9, 2nd paragraph states the exact opposite. Please clarify.

All tables in the module are in imperial. Most of the other learning modules are in imperial and metric. Why is it mixed? Wouldn't it be easier and more precisely for the trades using only one system (to avoid mistakes and misinterpretation)? Wouldn't it be easier to deal with only one system? Metric or imperial.
