What is 68 Fahrenheit in Celsius?
68 Fahrenheit = 20 CelsiusHow to convert 68 Fahrenheit to Celsius
0 degrees Fahrenheit is equal to -17.77778 degrees Celsius:
0 °F = -17.77778 °C
The temperature T in degrees Celsius (°C) is equal to 68 degrees Fahrenheit (°F) minus 32, times 5/9. To convert 68 Fahrenheit to Celsius we can use the formula below:
T(°C) = (68°F - 32) × 5/9
T(°C) = 20 °C
68 °F = 20 °C
We conclude that sixty-eight Fahrenheit is equivalent to twenty Celsius:
68 Fahrenheit is equal to 20 Celsius.

Definition of units
Let's see how both units in this conversion are defined, in this case Fahrenheit and Celsius:
Fahrenheit (°F)
The Fahrenheit scale is a temperature scale based on one proposed in 1724 by Amsterdam-based physicist Daniel Gabriel Fahrenheit (1686–1736), after whom the scale is named. It uses the degree Fahrenheit (symbol: °F) as the unit. Several accounts of how he originally defined his scale exist. The lower defining point, 0 °F, was established as the temperature of a solution of brine made from equal parts of ice and salt. Further limits were established as the melting point of ice (32 °F) and his best estimate of the average human body temperature (96 °F, about 2.6 °F less than the modern value due to a later redefinition of the scale). The scale is now usually defined by two fixed points: the temperature at which water freezes into ice is defined as 32 °F, and the boiling point of water is defined to be 212 °F, a 180 °F separation, as defined at sea level and standard atmospheric pressure. By the end of the 20th century, Fahrenheit was used as the official temperature scale only in the United States (including its unincorporated territories), its freely associated states in the Western Pacific (Palau, the Federated States of Micronesia and the Marshall Islands), the Bahamas, Belize, and the Cayman Islands. All other countries in the world now use the Celsius scale, defined since 1954 by absolute zero being −273.15 °C and the triple point of water being at 0.01 °C.
Celsius (°C)
The Celsius scale, also known as the centigrade scale, is an SI scale and unit of measurement for temperature. As an SI derived unit, it is used by most countries in the world. It is named after the Swedish astronomer Anders Celsius (1701–1744), who developed a similar temperature scale. The degree Celsius (symbol: °C) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval, a difference between two temperatures or an uncertainty. Before being renamed to honour Anders Celsius in 1948, the unit was called centigrade, from the Latin centum, which means 100, and gradus, which means steps. The Celsius scale was based on 0 °C for the freezing point of water and 100 °C for the boiling point of water at 1 atm pressure following a change introduced in 1743 by Jean-Pierre Christin to reverse the Celsius thermometer scale (from water boiling at 0 degrees and ice melting at 100 degrees).
