###### Skala Termometer

C : R : (F − 32) : (K − 273) = 100 : 80 : 180 : 100

Contoh

Sebuah benda memiliki suhu 60°C. Tentukan suhu benda pada skala:

(A)   Reamur

(B)   Fahrenheit

(C)   Kelvin

(A)   Reamur

\begin{equation*}
\begin{split}
\frac{60 - 0}{x - 0} & = \frac{100 - 0}{80 - 0} \\\\
\frac{60}{x} & = \frac{\cancelto {5} {100}}{\cancelto {4} {80}} \\\\
\frac {60}{x} & = \frac {5}{4} \\\\
5 \:.\: x & = 60 \:.\: 4 \\\\
5 \:.\: x & = 240 \\\\
x & = \bbox[5px, border: 2px solid magenta] {48^{\text{o}} \text{ R}}
\end{split}
\end{equation*}

(B)   Fahrenheit

\begin{equation*}
\begin{split}
\frac{60 - 0}{x - 32} & = \frac{100 - 0}{212 - 32} \\\\
\frac{60}{x - 32} & = \frac{\cancelto {5} {100}}{\cancelto {9} {180}} \\\\
\frac {60}{x - 32} & = \frac 59 \\\\
\cancelto {1} {5} \:.\: (x - 32) & = \cancelto {12} {60} \:.\: 9 \\\\
x - 32 & = 12 \:.\: 9 \\\\
x - 32 & = 108 \\\\
x & = \bbox[5px, border: 2px solid magenta] {140^{\text{o}} \text{ F}}
\end{split}
\end{equation*}

(C)   Kelvin

\begin{equation*}
\begin{split}
K & = C + 273 \\\\
K & = 60 + 273 \\\\
K & = \bbox[5px, border: 2px solid magenta] {333 \text{ K}}
\end{split}
\end{equation*}
