The temperature 104 degrees Fahrenheit is equivalent to 40 degrees Celsius. To understand this conversion, it's essential to know the formulas and differences between the Fahrenheit and Celsius scales. The Fahrenheit scale was introduced by Gabriel Fahrenheit in 1724, while the Celsius scale was developed by Anders Celsius in 1742. The Celsius scale is based on the freezing and boiling points of water, which are set at 0 degrees and 100 degrees, respectively. In contrast, the Fahrenheit scale sets the freezing point of water at 32 degrees and the boiling point at 212 degrees.
Temperature Conversion Formula
To convert temperature from Fahrenheit to Celsius, the following formula is used: °C = (°F - 32) × 5⁄9. Using this formula, we can calculate the equivalent of 104 degrees Fahrenheit in Celsius. Substituting 104 for °F, we get °C = (104 - 32) × 5⁄9 = 72 × 5⁄9 = 40. Therefore, 104 degrees Fahrenheit is equal to 40 degrees Celsius.
Importance of Temperature Measurement
Accurate temperature measurement is crucial in various fields, including medicine, chemistry, and environmental science. In medicine, body temperature is a vital sign that can indicate health status. Normal body temperature ranges from 97.7 to 99.5 degrees Fahrenheit (36.5 to 37.5 degrees Celsius). A temperature of 104 degrees Fahrenheit is considered high and may indicate fever or heat-related illness. In chemistry, temperature affects reaction rates and the state of matter. In environmental science, temperature plays a significant role in climate change and weather patterns.
| Temperature Scale | Freezing Point | Boiling Point |
|---|---|---|
| Fahrenheit | 32°F (0°C) | 212°F (100°C) |
| Celsius | 0°C (32°F) | 100°C (212°F) |
Temperature Measurement Tools
There are various tools used to measure temperature, including thermometers, thermocouples, and infrared thermometers. Thermometers are the most common tool for measuring temperature and can be digital or analog. Digital thermometers provide quick and accurate readings, while analog thermometers use a mercury or alcohol column to indicate temperature. Thermocouples are used to measure high temperatures and are commonly used in industrial applications. Infrared thermometers are non-contact thermometers that use infrared radiation to measure temperature and are often used in medical and industrial settings.
Temperature Units and Scales
There are several temperature units and scales, including Kelvin, Rankine, and Réaumur. The Kelvin scale is an absolute temperature scale that sets absolute zero at 0 Kelvin (-273.15°C or -459.67°F). The Rankine scale is similar to the Fahrenheit scale but sets absolute zero at 0 Rankine. The Réaumur scale is an obsolete temperature scale that was used in the past. Understanding the different temperature units and scales is essential for accurate temperature measurement and conversion.
- Fahrenheit scale: sets freezing point at 32°F and boiling point at 212°F
- Celsius scale: sets freezing point at 0°C and boiling point at 100°C
- Kelvin scale: sets absolute zero at 0 Kelvin
