Updates

Zip code look-ups are working again.

The widget now supports the Rankine, Delisle, Newton, Réaumur, and Rømer temperature scales.

How It Works

The Berka temperature scale has 200 degrees from the freezing point of water (-45 °B) to the boiling point of water (155 °B). The scale is adjusted so that 0 °B is exactly 22.5 °C or exactly 72.5 °F, which is approximately room temperature.

The following formulas are used to convert from Celsius, Fahrenheit, and Kelvin to Berka:

°B = (°C × 2) - 45
°B = [(°F - 32) × 10/9] - 45
°B = [(K - 273.15) × 2] - 45

The following formulas are used to convert from Berka to Celsius, Fahrenheit, and Kelvin:

°C = (°B + 45) × 1/2
°F = [(°B + 45) × 9/10] + 32
K = [(°B + 45) × 1/2] + 273.15
