Accuracy and rounding
Use exact formulas for cooking, weather, and thermostat settings. Round the final value to the nearest degree when precision is not important.
Temperature conversions use scale formulas with offsets. The calculator keeps the formula result and rounds only what is displayed.
For weather or cooking, whole degrees are usually enough. For science or equipment settings, keep at least one decimal in Fahrenheit.
