Conversion Formula
To convert Celsius to Fahrenheit, you can use the following formula:
Fahrenheit = (Celsius * 9/5) + 32
Explanation
To convert 10 degrees Celsius to Fahrenheit, we can use the formula mentioned above.
Fahrenheit = (10 * 9/5) + 32
Simplifying the equation, we get:
Fahrenheit = (18) + 32
Calculating further, we find:
Fahrenheit = 50
Therefore, 10 degrees Celsius is equal to 50 degrees Fahrenheit.
Answer
The correct answer is 50 (option D).

Note that these are temperature changes, not actual temperatures, so we do not first subtract 32°. To change from degrees Fahrenheit to degrees Celsius, we just multiply by 5/9:

To: To convert Fahrenheit to Celsius, use the formula (F - 32) × 5/9 = C.
Applying the values: - (80 - 32) × 5/9 = 48 × 5/9 ≈ 26.67
Rounding to the nearest whole number, 26.67°C is approximately 27°C.

Centigrade Scale
The Celsius temperature scale is still sometimes referred to as the Centigrade scale. This term was widely used before the name was officially changed to Celsius in 1948 to honor the Swedish astronomer Anders Celsius who first proposed the scale in 1742.
Origin of the Term
The term "Centigrade" comes from the Latin "centum" meaning one hundred and "gradus" meaning steps. It was used because the Celsius scale originally had 100 degrees between the freezing and boiling points of water.
Official Name Change
In 1948, the International Committee for Weights and Measures officially renamed the scale to Celsius to avoid confusion with the angular measurement unit also called the gradian. The Celsius scale is now widely used in scientific and everyday contexts.
Common Usage
Despite the official name change, the term Centigrade is still used by some people, especially in older texts or in informal settings. However, it is important to note that the correct and current name for the scale is Celsius.
