You would use either Fahrenheit, or Celsius. (I use F to measure my temp, but it could be different depending what country you live in)
For a healthy human, this would be
37 degrees Celsius
or
98.6 degrees Fahrenheit
It depends on what characteristic you want to measure! Its mass, its height, the amount of body fat, the fineness of its fleece?
Temperature is the measure of the internal kinetic energy of a body.
Lebron James is the best basketball player in the world
the body will not reach 102 degrees because the ambient temperature is lower.However, and I hope we are talking Fahrenheit here, should the body come into line with the ambient temperature and then exercise, it would be possible.As for the time that would take, there are too many factors that would meed to be considered, for instance, body mass, fat content, hydration levels etc. Plus you would need to consider where you will be taking the measurement, is it core temperature that you are interested in or skin temperature.Just out of curiosity, why the question?
A king's foot used to be the standard of measurement, now there is a Bureau of Measurements in the Washington DC that has standard measurement's that everyone else uses.
termometer
What kind of thermometer you use to measure the body temperature
Clinical thermometer
Types of Thermometers - ApplicationsClinical ThermometersThe clinical thermometers are used to measure the body temperature of the patient. There are again three types of clinical thermometers depending on the body part used to measure the temperature.Ear (Tympanic) thermometersHuman ear is located near the brain. This makes it an accurate point to measure the body temperature. The temperature of the eardrum is measured by the ear thermometers. However, the eardrum is most fragile and delicate body part. Therefore, the body temperature cannot be measured by touching the eardrum. For temperature measurement, infrared sensors are used to remotely sense the temperature of the eardrum. Thermopile, an infrared sensor, is commonly used in ear thermometer.Pacifier ThermometersThe pacifier thermometers are used to check the body temperature of babies or infants. They help measure the body temperature without irritating the baby. The thermometer is held in the mouth of the baby and the baby's natural sucking instinct is used to check its body temperature. The pacifier thermometers are very safe for checking the body temperature of babies.Underarm or Oral ThermometersThe underarm thermometers are kept in the underarms to measure the body temperature of the patient. Likewise, the oral thermometers are held in the mouth for temperature measurement.
Doctors use body temperature thermometers to measure body temperature.
Kelvin's is used to measure various things such as body heat, substances and many other things.
It depends on what characteristic you want to measure! Its mass, its height, the amount of body fat, the fineness of its fleece?
Heat is the energy transferred from one body to another as the result of a difference in temperature. Heat flows from a hotter body to a colder body when the two bodies are brought together. This transfer of energy results in an increase in the temperature of the colder body and a decrease in the temperature of the hotter body. Temperature is a measure of the average energy of the molecules of a body. It is expressed in terms of any of several scales, such as Fahrenheit, Celsius, or Kelvin.
heat is a energy and temperature is a measurement . (of how concentrated it is)
Measurement of human body temperature.
Tympanic and rectal... and in recent years, monitoring of urinary bladder temperature has become more common. Temperature-sensing indwelling urinary catheters allow continuous drainage of urine and continuous measurement of body temperature.
The normal core body temperature of a healthy, resting adult human being is stated to be at 98.6 degrees Fahrenheit or 37.0 degrees celsius. Though the body temperature measured on an individual can vary, a healthy human body can maintain a fairly consistent body temperature that is around the mark of 37.0 degrees celsius. The normal range of human body temperature varies due to an individuals metabolism rate, the higher (faster) it is the higher the normal body temperature or the slower the metabolic rate the lower the normal body temperature. Other factors that might affect the body temperature of an individual may be the time of day or the part of the body in which the temperature is measured at. The body temperature is lower in the morning, due to the rest the body received, and higher at night after a day of muscular activity and after food intake. Body temperature also varies at different parts of the body. Oral temperatures, which are the most convenient type of temperature measurement, is at 37.0 °C. This is the accepted standard temperature for the normal core body temperature. Axillary temperatures are an external measurement taken in the armpit or between two folds of skin on the body. This is the longest and most inaccurate way of measuring body temperature, the normal temperature falls at 97.6 °F or 36.4 °C. Rectal temperatures are an internal measurement taken in the rectum, which fall at 99.6 °F or 37.6 °C. It is the least time consuming and most accurate type of body temperature measurement, being an internal measurement. But it is definitely, by far, not the most comfortable method to measure the body temperature of an individual.
