How to convert from Celsius to Rankin?!?

Question

Just explain for me the method you've used.

Answer 1

T(Rankin)=T(Celcius) × 1.8 + 491.68

Answer 2

Formulae Conversion Factors

9/5 = 1.8    9/4 = 2.25    10/8 = 1.25

Fahrenheit Celsius  C = ( F - 32) / 1.8

Fahrenheit kelvin K = ( F + 459.67) / 1.8

Fahrenheit Rankine  Ra =  F + 459.67

Fahrenheit Réaumur  Re = ( F - 32) / 2.25  

Celsius Fahrenheit  F =  C × 1.8 + 32

Celsius kelvin K = C  + 273.15

Celsius Rankine  Ra =  C × 1.8 + 32 + 459.67

Celsius Réaumur  Re =  C × 0.8

kelvin Celsius  C = K - 273.15

kelvin Fahrenheit  F = K × 1.8 - 459.67

kelvin Rankine  Ra = K × 1.8

kelvin Réaumur  R = (K - 273.15) × 0.8

Rankine Celsius  C = ( Ra - 32 - 459.67) / 1.8

Rankine Fahrenheit  F =  Ra - 459.67

Rankine kelvin K =  Ra / 1.8

Rankine Réaumur  Re = ( Ra - 32 - 459.67) / 2.25  

Réaumur Celsius  C =  Re × 1.25  

Réaumur Fahrenheit  F =  Re × 2.25 + 32

Réaumur kelvin K =  Re × 1.25 + 273.15  

Réaumur

hope your math is good

Answer 3

Convert to Farenheight, then to Rankin.
