Units

Meteobreeze stores weather data in a canonical set of units so charts, alerts, and exports stay consistent no matter where the data comes from.

Canonical units

Meteobreeze stores:

• Temperature in °C
• Wind speed and gusts in m/s
• Pressure in hPa
• Rain rate in mm/h
• Rain total in mm
• Wind direction in degrees
• Solar radiation in W/m²
• UV index as a unitless index
• Timestamps in UTC

Why this matters during import

When you import historical data or connect a live source, Meteobreeze needs to know the unit format your source uses. That lets it convert the incoming values into the canonical storage units above.

For example:

• °F temperature values are converted to °C
• mph, km/h, and kn wind values are converted to m/s
• inHg pressure values are converted to hPa
• Rain values in inches are converted to mm

If the source unit is wrong, the imported values will be wrong too.

What to do next

If you are importing CSV data, make sure each mapped column has the correct unit. If you are setting up a live source, use the source guide to send values in the correct format.
