-40
This is the only temperature where it coincides between the Celsius and Fahrenheit scales. 40 degrees below zero on the Celsius scale is 40 degrees below on the Fahrenheit scale.
A substance melts at 375 Celsius. What is the melting point on the Fahrenheit scale?
Both scales were developed in the early 18th Century. The Fahrenheit scale was proposed by Daniel Fahrenheit. The freezing point of brine set the 0 point. 180 degrees separated the freezing point of water (32 degrees) from the boiling point (212 deg). Anders Celsius introduced the Centigrade scale in which the freezing point was 0 deg and the boiling point was 100 degrees. Centigrade was later renamed Celsius. The Celsius scale is the international standard, used by most countries and scientific communities in all countries. There are some countries, however, that have not fully adopted the Celsius scale, so the Fahrenheit scale remains in use today.
at -40 on each scale.
On the Celsius scale, the freezing point is 0°C and the boiling point 100°C. On the Fahrenheit scale, the freezing point is 32°F and the boiling point 212°F.
The units, in this case, are kelvin, degrees Fahrenheit, and degrees Celsius.
160 Celsius = 320 Fahrenheit
-40 F = (-40 -32)x 5/9 C = -72 x 5/9 = -40 C
There is a temperature scale called Celsius. On the Celsius scale, the freezing point of water is 0o and the boiling point of water is 100o (in comparison to the Fahrenheit scale, in which water freezes at 32o and boils at 212o). Also note: the Celsius scale is sometimes called the Centigrade scale, although Celsius is the correct term.
There are four units for temperature: Celsius, Kelvin, Fahrenheit, and Rankine. The Kelvin scale is the same as the Celsius scale, just with the zero point being absolute zero. The Rankine scale is the same thing for the Fahrenheit scale. ■
50 celsius Hotter on Celsius Scale
Most of the world now uses the Celsius scale where the boiling point of water is 100 degrees Celsius.
