One of the most common devices for measuring temperature is the glass thermometer . This consists of a glass tube filled with mercury or some other liquid, which acts as the working fluid. Temperature increase causes the fluid to expand, so the temperature can be determined by measuring the volume of the fluid.
What are the 3 ways to measure temperature?
There are three main scales commonly used in the world today to measure temperature: the Fahrenheit (°F) scale, the Celsius (°C) scale, and the Kelvin (K) scale .

Is 37.5 a fever in adults?
A high temperature is usually considered to be 38C or above . This is sometimes called a fever. Many things can cause a high temperature, but it's usually caused by your body fighting an infection.

What is a normal forehead temperature?
The normal temperature range on the forehead is approximately between 35.4 °C and 37.4 °C .
What are the two types of temperature?
Temperature Scales. There are three temperature scales in use today, Fahrenheit, Celsius and Kelvin . Fahrenheit temperature scale is a scale based on 32 for the freezing point of water and 212 for the boiling point of water, the interval between the two being divided into 180 parts.
What are the most important methods of measuring temperature?
- Thermocouples.
- Thermistors.
- Resistance temperature detector (RTD)
- Pyrometer.
- Langmuir probes (for electron temperature of a plasma)
- Infrared thermometer.
- Other thermometers.
What are the instrument used for measuring temperature?
The instrument used to measure temperature is called a thermometer . It is a combination of two words thermo and meter meaning heat and measurement, respectively. The most common form of thermometers used are mercury thermometers.
Is 100 a normal body temperature?
Here are some other definitions related to body temperature: Normal : temperatures between 97.7°F (36.5°C) and 99°F (37.2°C) Low-grade fever: temperatures between 99°F (37.2°C) and 100.4°F (38°C) Fever (pyrexia): temperatures between 100.4°F (38°C) and 105.8°F (41°C)
Which part of body temperature is most accurate?
Rectal temperatures are considered most accurate indication of the body's temperature. Oral and axillary temperature readings are about 1⁄2° to 1°F (. 3°C to . 6°C) below rectal.
What is a normal body temperature chart?
| Body temperature chart for adults | Hypothermia < 35.0° < 95.0° | Normal 36.5° – 37.5° 97.7° – 99.5° | Hyperthermia (low-grade fever) > 38.3° > 100.9° | Hyperpyrexia (high fever) > 41.5° > 106.7° |

Is 37.3 a fever in adults?
In most adults, an oral or axillary temperature above 37.6° C (99.7°F) or a rectal or ear temperature above 38.1°C (100.6°F) is considered a fever. A child has a fever when his or her rectal temperature is higher than 38°C (100.4°F) or armpit (axillary) temperature is higher than 37.5°C (99.5°F).
Is 37.2 a fever?
What are the symptoms of a fever? Normal body temperature ranges from 97.5°F to 98.9°F (36.4°C to 37.2°C). It tends to be lower in the morning and higher in the evening. Most healthcare providers consider a fever to be 100.4°F (38°C) or higher.
