What is 19 degrees Celsius in Fahrenheit?
The Correct Answer and Explanation is:
To convert 19 degrees Celsius to Fahrenheit, we use the standard formula:
F = (C × 9/5) + 32
Substitute 19 for C:
F = (19 × 9/5) + 32
F = (171/5) + 32
F = 34.2 + 32
F = 66.2
Answer: 19 degrees Celsius is equal to 66.2 degrees Fahrenheit.
Explanation
Temperature can be measured using different scales. The two most commonly used are Celsius and Fahrenheit. The Celsius scale is used in most parts of the world, especially in scientific contexts and countries that follow the metric system. The Fahrenheit scale is mostly used in the United States for everyday temperature reporting such as weather forecasts and cooking.
To convert a temperature from Celsius to Fahrenheit, the formula used is:
Fahrenheit = (Celsius × 9/5) + 32
This formula is derived from the relationship between the freezing and boiling points of water on both scales. On the Celsius scale, water freezes at 0 degrees and boils at 100 degrees. On the Fahrenheit scale, water freezes at 32 degrees and boils at 212 degrees. The interval between these points is 100 degrees on the Celsius scale and 180 degrees on the Fahrenheit scale. The ratio of 180 to 100 simplifies to 9/5, which is used in the formula. The “+ 32” part accounts for the difference in the starting points of the two scales.
When we apply this formula to convert 19 degrees Celsius, we multiply 19 by 9/5 to account for the difference in scale, which gives us 34.2. We then add 32 to align with the zero point of the Fahrenheit scale. The final result is 66.2 degrees Fahrenheit.
Understanding how to convert between these units is useful for interpreting weather reports, reading recipes, or working with international standards. It helps bridge the gap between the metric and imperial systems.
