°C to °F settlement converter
Most 5-minute station readings are sent in whole °C, so one reading can mean two whole °F values. Type a reading to see which °F values it fits.
How this is worked out
A station measures in °F, rounds to whole °C for the 5-minute message, and the daily climate report rounds the °F value half up. So a whole °C value fits every whole °F whose °C rounds to it. Hourly reports carry tenths of a °C, which pin one exact °F.
