What unit preferences can I set and how do they affect displayed data?
You can customize measurement units in Settings → Localization → Unit Preferences. These settings control how values are displayed across dashboards, reports, and exports.
Available unit preferences
Energy unit
- kWh (kilowatt-hours) — default, standard for most European utility billing
- MWh (megawatt-hours) — useful for large buildings or portfolio-level views where kWh values are very large (1 MWh = 1,000 kWh)
Volume unit (water and gas)
- m³ (cubic meters) — default, standard in Europe
- Liters — more granular for small volumes
- US gallons or UK gallons — for non-metric regions
Temperature unit
- Celsius — default, used in most countries
- Fahrenheit — for US-based users
Area unit
- m² (square meters) — default, used for building areas, local sizes, and cost-per-area calculations
- sqft (square feet) — for non-metric regions
How these affect your data
Your selected units are display preferences. The system stores all data in standard SI units internally (watt-hours for energy, cubic meters for volume, square meters for area). When displaying values, it converts to your preferred unit on the fly.
Example: If a meter reading is stored as 500,000 Wh internally:
- With energy_unit = "kwh": displayed as 500 kWh
- With energy_unit = "mwh": displayed as 0.5 MWh
What about uploaded invoices?
Invoice data is stored using the units from the document. The system extracts consumption as-is (energy in watt-hours, water in cubic meters). Your unit preference only affects how these values are displayed in charts and reports — it does not modify the stored data.
Where to configure: Settings → Localization tab → scroll to "Unit Preferences" section. Remember to click "Save Settings" after making changes.
