Units

Units are display only. The engine does all of its math in metric internally and converts at the boundary, so switching units changes what you read, not how LocalSky waters. (Zone area is the one value you enter yourself, so its unit does feed the water math; see Zones.)

Find the control under Settings, then Units. It has two independent layers, picked by the “Applies to” switch at the top.

Household default (whole deployment)

Imperial or Metric for the whole install. It is stored in /data/localsky.toml as deployment.units and travels on the irrigation snapshot, so every device that follows the household updates on the next tick. This layer has an explicit Save button, because it changes shared server config.

• Imperial: F, inches, mph, inHg, miles, square feet.
• Metric: C, mm, km/h, hPa, km, square meters.

The setup wizard pre-selects this from your location.

This device only (per browser)

A single device can opt out of the household default and keep its own units, saved in that browser’s localStorage. There is no Save button here: each pick persists the moment you make it, and a short “Saved on this device” line confirms it. Your other devices and the household default are untouched.

Pick a whole system (Imperial or Metric), or choose Custom to set each measurement on its own: temperature, rainfall, wind speed, pressure, distance, and zone area. Switch back to “Household default” and the per-device keys are cleared, so the device follows the deployment again.
