Different facilities use different measurement systems. North-American
aerospace shops live in °F + mils + gallons + lb; ROW + most metric
shops use °C + microns + litres + kg. Add company-level defaults so
each shop picks its units once; new records inherit them automatically.
**Settings on res.company** (7 Selection fields):
• x_fc_default_temp_uom — °F / °C
• x_fc_default_thickness_uom — mils / microns / inches / mm
• x_fc_default_volume_uom — US gal / litres / Imp gal
• x_fc_default_mass_uom — lb / kg / oz / g
• x_fc_default_pressure_uom — psi / bar / kPa
• x_fc_default_current_density_uom — A/ft² (ASF) / A/dm² (ASD)
• x_fc_default_area_uom — sq in / sq ft / cm² / m²
All default to North-American aerospace conventions (F, mils, gal, lb,
psi, asf, sq_in) — admins flip them once during onboarding via
Settings → Fusion Plating → Units of Measure.
**Per-record use** (this round)
• mrp.workorder.x_fc_bake_temp_uom (°F / °C) — defaults from company,
operator can override per WO if a specific bake needs a different
unit (rare but allowed).
• Bake-finish gate error message now reports the actual unit:
"Bake Temp (°F)" or "Bake Temp (°C)" instead of hard-coded F.
• Form: Bake Temp + Temp Unit picker side-by-side in the bake group.
**Settings UI** — new "Units of Measure" block on Settings → Fusion
Plating page with help text per unit explaining where each is used.
**Verified end-to-end** (scripts/fp_uom_smoke.py):
• All 7 defaults populate with NA-aerospace defaults
• Switching company default to °C makes a NEW WO inherit °C
• Existing WOs keep their stored °F (no surprise mutation)
**Roadmap (deferred to next round)** — wire the same default-from-company
inheritance to:
• fp.bake.oven.target_temp (currently no UoM)
• fp.bake.window.bake_temp (currently no UoM)
• fp.coating.config.bake_temperature (currently no UoM)
• fp.tank.volume already has volume_uom; default from company
• fp.bath.log chemistry readings already use parameter.uom; align
with company default for new params
The settings + framework are now in place — adding more per-record uom
fields is mechanical from here.
