how many decimal should a body thermometer have and why?"?

Question

would a thierd decimal digit be useful? or we would not need it !

Answer 1

Just one decimal will be enough. The baseline of body temperatures uses ranges with whole numbers. 0.5 difference could sometimes be considered as a considerate to what is normal or abnormal. Any fraction of a whole is not considered as a big deal so what benefit it will give to have more decimal places? Anyway, what the temperatures measure is just an approximation of body temperature and not really reflecting 100 % accuracy of the actual body temperature. The body has the ability to change the temperature in less than a second though the change can be in a small fraction value. So do you think a fraction difference in temperature measurement expressed in a small fraction unit would give significance?

Answer 2

In my humble opinion, one decimal place is adequate. Since no difference in medical treatment will be decided based on a 0.1 change in temperature, it makes little sense to show a temp as 100.55 F as opposed to 100.5 F or 100.6 F (or in Celcius either 38.5C - 38.6C). Generally speaking, in science, more decimals are used when the accuracy is needed to make critical decisions. e.g. the angle and strength of radiation to a brain tumor.

Answer 3

The thermometer should have decimal upto 1 digit because to measure accurate body temperature we need a precision upto 1 decimal place

Answer 4

i do not recognize yet even if it really is for fertility topics you need to look up Babycomp and/or LadyComp... both intense priced, yet artwork large. they are basal thermometers with pcs in them that anticipate your fertile circumstances with outstanding accuracy...

Answer 5
