If you don't mind, since you don't seem to understand the way metric was basically created i will copy pasta my response to a similar topic in another threadSigna said:Damn, now I need to look up later where and how it scales. I've always thought the numbers were constant....Sinclose said:Yup, that's exactly what I meant. Temperature can be expressed in terms of energy-which determines how hot or how cold an object is-and 300F does NOT mean that it contains 3x the energy at 100F. However, an object at 30 degrees Celsius will have 3x the energy of an object at 10 degrees Celsius.
(Please also note that I'm overly simplifying my examples for the sake of convenience)
Waiiiiiit... How does the Celsius conversion work then? If Celsius stays constant, then whey does the conversion formula stay constant too? I'm not looking it up now, but I thought the conversion was something like F=C2.5+32 or something like that. That would have to change at some point in the higher digits if one degree in Celsius doesn't stay 2.5 degrees in Fahrenheit.
Assuming you're right though, it does change my argument for Fahrenheit. I'm not going to back a system that is inconsistent! That's the whole point of a measurement system!
"1 meter = original definition: Distance travelled in one wavelength (vacuum) of Krypton-86 radiation
new revised definition: Distance travelled by light (vacuum) in 1/299792458 to a absolute uncertainty of .1nm
This was decided to be the base for one meter by the CGPM (General Conference on Weights and Measurements original name is french hence mismatching initials). This was chosen after some consideration, they wanted a practical size measurement that they could relate to a natural aspect (decided to be a wavelength since its easily measurable).
In order to facilitate the use of measurements among the scientific community, a base of 10 was decided.
Hence the meter was divided into 100 parts each named a centimetre. A cube of dimensions 10x10x10 centimetres was created and named a cubic decimetre. This amount was quantified as 1 Liter.
This measurement was then filled with water at a temperature of 4 degrees Celsius (temperature of melting ice, so the water is neither compressed nor expanding), and the resulting weight named a Kilogram. Since 1 Liter was defined as 1000cm^3 weighting 1 Kilogram this means that 1Kg divided by 1000 would be found by 1cm^3 now named 1 gram.
The point im trying to make here is that these measurements are not by occasion, they were specifically designed to improve the accuracy of our calculations by clearly defining a physical constant (Krypton radiation/speed of light/water temp) as it's foundation. The fact that each part was divided into base tens was merely for it's ease of use, but the measure itself (metre) has a unchangeable definition."
Regarding Celsius it is merely a division of 100 units between the temperature at which water freezes and boils, at higher number it doesn't hold any specifics (-273.15 C is absolute zero) but it holds the same unit difference as Kelvins (1 C = 1 K) so it is still relevant scientifically.
