On the Fahrenheit scale: O°F 32°F freezing point of water (equivalent to 0°C) 212°F boiling point of water (equivalent to 100°C) Fahrenheit scale (32°F....212°F) but is 100 degrees in the Celsius scale (0°C..T00 C). As with using the metric system, it is important in the sciences to learn to use and report temperature readings using the Celsius scale since it is more universally used than the Fanrenniore scale. The formulas used to convert between these two temperature scales are listed below. When converting from°F to°C °C= ('F - 32) 1.8 °C=5/9('F - 32) -OR- When converting from°C to°F °F = (°C x 1.8) + 32 °F = (°C x 9/5) + 32 -OR- Use the above equations (either the decimal or fraction form) to complete the following conversions.
