It's actually cool, but comfortable especially in our summer time here in Southeast, TX.
68 degrees Fahrenheit is equivalent to 20 degrees Celsius.
It's easy to convert from Celsius to Fahrenheit by yourself. Tf = (9/5)*Tc+32, where Tc = temperature in degrees Celsius, Tf = temperature in degrees Fahrenheit. 20 C is 68 F.
It has been known to get down as low as -68 degrees C (-90.4 degrees F) in the Arctic.
72 F is a pleasant room temperature, neither hot nor cold.
No. According to NOAA: "Temperature: optimum for [oyster] larvae is 68-90.5 degrees F (20-32.5 degrees C), for adults 68-86 degrees F (20-30 degrees C); adults can tolerate 35.6-96.8 degrees F (2-36 degrees C) and up to 120.2 degrees F (49 degrees C) for short periods. Larvae can grow in water as cold as 63.5 degrees F (17.5 degrees C). Antarctic waters -- the Southern Ocean -- are as cold as 27 degrees F, because of the minerals in the water. Southern Ocean warmest temperatures are 28 degrees C to 50°F
Hot and cold are comparative terms. 36 degrees F is considerably colder than 36 degrees C
68 degrees Fahrenheit = 20 degrees Celsius
For a human being, cold. For a domestic food freezer, just about right.
Well 30 C is hot, 30 F is cold. That depends if it is 30 degrees Celsius or 30 degrees Fahrenheit. If it was 30 degrees C then it would be hot because it is around 85 degrees F. If it was 30 degrees F....then it would be darn cold.
In the weld area the steel is molten 2800 degrees F +. The arc can reach 5000 degrees F +. Surrounding areas anywhere from cold to 2800 degrees F.
Temperatures can plunge to below -120 degrees F in the Antarctic Desert or be as warm as +134 degrees F in the Mojave Desert.
Mars can have temperatures as low as -195 degrees Fahrenheit (-125 degrees Celsius) at the poles during winter, while daytime temperatures near the equator can reach about 70 degrees Fahrenheit (20 degrees Celsius). Overall, Mars' average temperature is around -80 degrees Fahrenheit (-60 degrees Celsius).
