Formula for converting degrees Celsius to degrees Fahrenheit is:<\/span><\/p>

\u00b0F = (\u00b0C \u00d7 9\/5) + 32<\/b><\/p>

We will now convert it step by step.<\/span><\/p>

Step 1<\/b><\/p>

First, multiply the degree in Celsius by 9.<\/span><\/p>

21 \u00d7 9 = 189<\/span><\/p>

Step 2<\/b><\/p>

Then divide the answer by 5.<\/span><\/p>

189 \u00f7 5 = 37.8<\/span><\/p>

Step 3<\/b><\/p>

Add 32.<\/b><\/p>

37.8 + 32 = 69.8\u00b0F<\/span><\/p>

Conclusion<\/b><\/p>

21\u00b0C = 69.8\u00b0F<\/span><\/p>

This is the simplest way of converting the temperature from degrees Celsius to degrees Fahrenheit.<\/span><\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
