### 4/5 — Metric ONLY please !

*2024-10-06, version 4.1.10*

Great app, Thanks !

However, I have zero use for, or interest in, any imperial measurements whatsoever.  This appears here and there seemingly at random and these numbers mean absolutely nothing to me.  They may as well be hieroglyphs.

Can you please turn on a setting for us non US users, with consistent metrics only ?
