In the southern part of Finland, -15 °C (5 °F) is considered the limit of severe frost. The thermometer in the picture shows -17 °C (1.4 °F). The English word "frost" has 2 base meanings that are related to each other but nevertheless sufficiently different: temperature of air below the freezing point of water (ca 273 K)
"Degree" in this case can refer to degree Celsius or degree Fahrenheit. When based on Celsius, 0 degrees of frost is the same as 0 °C, and any other value is simply the negative of the Celsius temperature. When based on Fahrenheit, 0 degrees of frost is equal to 32 °F. Conversion formulas: T [degrees of frost] = 32 °F − T [°F]
