20C

20°C is most commonly used to denote a temperature of twenty degrees Celsius. The Celsius scale is widely used in science, weather reporting, and everyday life, with 0°C at the freezing point of water and 100°C at the boiling point at standard atmospheric pressure.

20°C equals 68°F and 293.15 K. The Fahrenheit value is calculated as (20 × 9/5) + 32; Kelvin is Celsius + 273.15.

In practical terms, 20°C is often described as room temperature. The exact range depends on context, but 20–25°C is a common reference range in laboratories, kitchens, and consumer product specifications.

The notation "20°C" may also appear as a product code, model number, or shorthand in various technical documents. In those uses, its meaning is determined by the associated system or catalog.
