In previous days the thermometer was only used for measuring human body temperature and atmospheric temperature but now days due to drastic industrial developments it is essential to measure temperature of various situations and conditions much accurately and precisely. Under some conditions heat from the measuring instrument can cause a temperature gradient so the measured temperature is different from the actual temperature of the system. Temperature is the measure of heat in the body. The normal body temperature when measured from the rectum should be 996 degrees fahrenheit. 2 normal human body temperature is 368 07 c or 982 13 f. The si unit used to measure the temperature in kelvink.
It was created by the german scientist daniel gabriel fahrenheit in the early 18th century and adapted its measurements standards from a previous scale created by ole roemer. Conditions during high or low body temperature. However for those lacking this talent there are a variety of instruments at hand to help determine body temperature. Ear temperature measurement may be acceptable for observing trends in body temperature but is less useful in consistently identifying fevers. When the temperature exceeds 996 degrees fahrenheit the body is said to be in a feverish state. The fahrenheit scale of temperature is the common form of temperature measurement used in the united states and some parts of the caribbean.
The instrument which is used for measuring temperature is a thermometer. Until recently direct measurement of core body temperature required surgical insertion of a probe so a variety of indirect methods have commonly been used. Types of instruments used in measuring body temperatures. Some of these instruments can be found at home while others are more likely to be found in a doctors office or hospital. Kelvin k is the international system of units si of temperature other than kelvin temperature is measured in celsius scale c and fahrenheit scale f. We can easily convert one unit of temperature into another by using some calculations.
The measurement is taken from the rectum and though accurate this technique can be very inconvenient. Temperature characterizes the body as hot or cold. We can calibrate temperature in different scales and in different units according to our requirements. The other scales used to measure the temperature are celsius or fahrenheit. To achieve required accuracy and precision of temperature measurement different types.
