What is temperature and what unit is it measured in?
Physicists measure temperature on the Kelvin scale, which is marked in units called kelvins, with the lower limit on the scale of 0 kelvin and known as absolute zero. The most commonly used temperature scales are Celsius (°C) (the unit is also known as centigrade), and Fahrenheit (°F).

What are the four units of temperature?
There are three temperature scales in common use today: kelvin (K), centigrade or Celsius (C), and Fahrenheit (F). A fourth scale, known as the Rankine (R) temperature scale, is less often used. The kelvin is the unit of temperature in the International System of Units ( SI ).
How is temperature measure?
Temperature is measured with a thermometer. Thermometers are calibrated in various temperature scales that historically have used various reference points and thermometric substances for definition. The lowest theoretical temperature is absolute zero, at which no more thermal energy can be extracted from a body.
What are the different units of temperature?
Temperature can be measured in Kelvin, Celsius, Fahrenheit, Rømer, Réaumur, Newton, Delisle and Rankine. The SI unit for temperature is Kelvin.
What is the standard SI unit for temperature?
The basic unit of temperature in the SI is the Kelvin (symbol “K”). Generally, temperature is measured with thermometers, which may be calibrated to a variety of temperature scales.
What is the basic unit of measurement?
The International System of Units (SI), the official system of measurement in almost every country in the world, is based upon the metric system. In the metric system, each basic type of measurement (length, weight, capacity) has one basic unit of measure (meter, gram, liter).
What is the SI unit for T?
The SI symbol for the tonne is “t”, adopted at the same time as the unit in 1879. Its use is also official for the metric ton in the United States, having been adopted by the United States National Institute of Standards and Technology. It is a symbol, not an abbreviation, and should not be followed by a period.
