Well here are some more helpful temperature conversions:. Fahrenheit F is the unit of temperature for the Imperial System of Measurement. This system is based off the temperature scale from physicist Daniel Gabriel Fahrenheit. In the Fahrenheit system the freezing point of water is 32 degrees F and the boiling point of water is at degrees F. For example I asked a few people and the conversion formula is the first thing that comes to mind - and how hard it is to remember.
The result won't be accurate but it does provide an approximate number that's "good enough" in everyday situations. The accurate answer is 77F but if you don't have a calculator handy and can't multiply and divide using fractions then this formula will give you a good idea that you can use in everyday situations. Many trace this number back to an book on medical thermometry by a German physician named Carl Reinhold August Wunderlich who measured the underarm temperatures of thousands of people.
Readers seem to have taken away the monolithic Even accounting for that variation, a recent study suggested that, across the population, core temperatures have declined about 0. The researchers acknowledge these observed reductions could be the result of changes in equipment and measurement technique. But they suggest the reduction could also reflect physiological shifts in metabolic rate and reductions in inflammation related to underlying medical conditions that people manage more effectively now than in the past.
A temperature reading will differ depending where on the body you measure it ; some of the common sites include in the mouth, in the ear, under the armpit, on the forehead, or rectally. Each of these locations will have slightly different normal values.
Temperature measurements — like oral or rectal — taken closer to the sites of more energy use and will produce more heat, resulting in higher temperature readings.
Body temperature is a byproduct of your metabolism. Metabolism is the way your body turns fuel — the carbohydrates, fats and proteins from the food you eat — into usable energy.
Digesting food, physical activity and infection increase the metabolic rate and can all raise your temperature. Babies may have slightly elevated normal body temperatures and caloric needs as a result of increased metabolic rate to support growth and development, while seniors may have slightly lower body temperatures due to lower rates of cellular growth and repair.
In addition to changes that occur as the result of age, everyone has variation throughout the day based on their circadian rhythms. Both the book by Wunderlich and more recent research have demonstrated that people typically experience their lowest body temperatures overnight. Medical practitioners generally classify fever as a temperature greater than
