Previously, `UNIT_G` was used for g-force with the correct symbol `g`, `UNIT_GR` for gram (as in kilogram) with the incorrect symbol `G` (which would be correct for Gauss), and `UNIT_GS` for Gauss with symbol `Gs` (which is an uncommon but correct symbol). To avoid confusion between G-Force, Gauss, and Gram the units have been renamed to `UNIT_G_FORCE`, `UNIT_GRAM`, and `UNIT_GAUSS`. In addition, gram now uses the correct symbol `g` and Gauss uses `G`.
