Fahrenheit, Celsius or Centigrade, Kelvin, Rankine, Reaumur, and others.
Fahrenheit scale says that 32o is the freezing point of water at 14 psi of air.
Celsius/Centigrade, says that the freezing point of water is 0oat 14psi.
Kelvin says that 0o is absolute zero; meaning that nothing can get colder than this: in Fahrenheit scale this temp. is 459o below zero.
Most thermometers have both Fahrenheit and Celsius scales on them.
Fahrenheit is marked with 'F' and Celsius is marked with 'C'.
Also I might mention that Celsius is part of the metric system, and is used in most countries is the world. However, Fahrenheit is part of the English system, and is used still in the United States.
The temperature scale used in HVAC in the US is Fahrenheit. This scale is commonly used for setting thermostat temperatures and reading room temperatures in buildings.
Yes. All scientists that work in the US use the Celsius scale.
When you are in the US or its territories.
In the short scale (as used in the US): 9 In the long scale (as used in Europe): 12
It depends on which scale you're talking about. The original Fujita scale was first used in 1971. The Enhanced Fujita scale was first used in 2007.
Fahrenheit.
Fahrenheit.
There are a few temperature scale that science use offten. The most common scale is a centigrade scale.
1 billion in numbers is 1000000000 in the short scale, such as used in the US, and 1000000000000 in the long scale, such as used in the UK.
Fahrenheit.
13,700,000,000 in the short scale, used in the US, and 13,700,000,000,000 in the long scale, used in the UK largely until 1974. The UK now uses the short scale, but some residual use of the long scale still exists.
For common weather measurements Fahrenheit is used in the US. For scientific purposes both the Fahrenheit and the Celsius scale are used.
