Final answer:
Convert 15°C to Fahrenheit, multiply 15 by 9/5 to get 27, and then add 32 to get the final result: 59°F. Converting between Celsius and Fahrenheit involves using a scale conversion factor of 9/5 or 1.8, reflecting the difference in how each scale defines the freezing and boiling points of water.
Step-by-step explanation:
To convert the temperature from Celsius to Fahrenheit, we use the given formula: F = (9/5)C + 32. To calculate the temperature in Fahrenheit when the temperature in Celsius is 15°C, we plug 15 into the formula.
-
- Multiply the Celsius temperature by 9/5 (which is the same as 1.8). So, 15°C × (9/5) = 27.
-
- Add 32 to this product to get the temperature in Fahrenheit. Therefore, 27 + 32 = 59°F.
As a result, 15°C is equal to 59°F.
Understanding the relationship between the Celsius and Fahrenheit scales is essential for temperature conversions. The Celsius scale, also known as the centigrade scale, is based on the properties of water, with 0° marking the freezing point and 100° the boiling point, whereas the Fahrenheit scale has 32° and 212° as the respective points for water's phase changes.
This difference results in the need to multiply by a factor of 9/5 (or 180/100) when converting from Celsius to Fahrenheit.
