Metric and imperial units

The planner can show lengths in metric (mm) or imperial (inches). Metric is the default.

Switching units

You can switch units in three places, all backed by the same per-account preference:

• the mm / in pill in the editor's status bar (bottom, next to the SNAP indicator),
• the Layout settings popover (the gear in the tool rail), and
• the planner profile → Editor defaults.

It flips every length the planner shows at once:

• the cursor position readout,
• the inspector's dimensions (position, length, radius, arc length, rise, join gaps),
• the catalogue tile dimensions ("168 mm" ⇄ "6.6 in"),
• the scale bar,
• validation messages, and
• the New layout, snap-step, and deck-elevation input fields.

Angles (°) and grade (%) don't change — they're the same in both systems.

Metric stays the source of truth

Everything the planner stores and computes — piece geometry, snapping, joins, and every export — is always in millimetres. Imperial is purely how the numbers are displayed; when you type a value in inches, it's converted straight back to millimetres. So switching units never moves a piece or changes a layout, and a plan made in inches is identical to the same plan made in millimetres.

Where the choice is saved

The unit choice is yours, not the layout's. When you're signed in it's saved to your account and follows you across devices; offline or signed out, it's remembered on the device you're using. Either way it defaults to metric until you change it.
