Using the formula $C=\frac{5}{9}(F-32)$ or $C=\frac{F-32}{1.8}$, for $F=21$, we get $C=\frac{5}{9}(21-32) = \frac{5}{9}(-11) = -6.1^{\circ}C$.

Convert to Celsius C=59( F−32)\mathrm{C}=\frac{5}{9}(\mathrm{~F}-32)C=95​( F−32) Or C=F−321.8\mathrm{C}=\frac{\mathrm{F}-32}{1.8}C=1.8F−32​ Round Your Answer to the Nearest Tenth If Necessary
