In the metric system of weights and measures, temperature is measured in degrees Celsius (°C) instead of degrees Fahrenheit (°F). To convert between the two systems, we use the equations. C =5/9 (F-32) and F = 9/5C+32. In each exercise, convert to the other system. Round answers to the nearest tenth of a degree if necessary. 20°C

Verified step by step guidance

1. Identify the given temperature in Celsius: 20°C.
2. Use the conversion formula from Celsius to Fahrenheit: $F=\frac{9}{5}C+32$.
3. Substitute the given Celsius temperature into the formula: $F=\frac{9}{5}\times 20+32$.
4. Calculate $\frac{9}{5}\times 20$ to find the product.
5. Add 32 to the product from the previous step to find the temperature in Fahrenheit.

Key Concepts

Temperature Conversion

Temperature conversion involves changing a temperature value from one scale to another, such as from Celsius to Fahrenheit or vice versa. The formulas used for these conversions are derived from the linear relationship between the two scales, allowing for accurate transformations based on specific reference points.

Celsius and Fahrenheit Scales

The Celsius (°C) and Fahrenheit (°F) scales are two different systems for measuring temperature. Celsius is based on the freezing and boiling points of water (0°C and 100°C), while Fahrenheit is based on a different set of reference points (32°F and 212°F). Understanding these scales is crucial for performing conversions accurately.

Rounding Numbers

Rounding numbers is the process of adjusting a numerical value to a specified degree of precision, often to make it simpler or more understandable. In the context of temperature conversion, rounding to the nearest tenth means adjusting the result to one decimal place, which is important for clarity and accuracy in reporting temperature values.
