Temperature scales is different scales that are used to measuring temperature. However, because temperature scales can be diffcult to use if you are moving from one scale to another, different scales are used in different situations. For instance, the Fahrenheit scale is used in oven to cook foods while the Celsius scale are used in weather reports and cookbooks.
Different field of study use different temperature scales because some fields of study require different starting point and degree of precision different than others. For instance, cooking and weather use the Celsius scale due to the relationship between the property of water and the Celsius scale; however, the Kelvin scale is used in the fields of physics and chemistry because it start at absolute zero (the point at which the molecule in a substance have the least amount of motion) and it does not use negative number due to this starting point. The three main formula for converting temperatures are as follows: to convert a temperature from Celsius to Fahrenheit, multiply the Celsius value by 1.8 and add 32 to the result.
Temperature Scales and How to Convert Them
To convert from Fahrenheit to Celsius, subtract 32 from the value in Fahrenheit and divide that result by 1.8. To convert to the Kelvin scale, either add or subtract 273 from the Celsius value because the size of one degree on the Kelvin and Celsius scale are equal to each other. The master table in the infographic display many of the most important and recognized temperatures.
For instance, the table include temperatures for absolute zero, the boiling point of liquid nitrogen, and the surface of the sun. Furthermore, such a table make it easy to recognize patterns in the scales; for instance, any value related to water will be a round number on the Celsius scale, but may be an awkward number on the other scales. Additionally, the table display the different categories of temperatures (cooking, weather, human health) which make it easy to recognize whether a given temperature is normal or extreme.
Cooking temperatures must be precise because each type of food require a specific temperature to ensure the health of the eater. For instance, fish, ground meat, and poultry all require the same temperatures to be considered safe to eat, yet these temperatures is all close to one another. Additionally, the different baking process for cakes and bread require different temperatures to properly set and cook the foods.
Finally, candy recipes require precise temperatures to affect the texture of the candy that is made. Each category is separated on the infographic so cooks can move between the Fahrenheit and Celsius scale without making an error in the recipe. Weather temperatures have specific value on all three scales that is associated with each of the seasons of the year.
For instance, winter temperatures are cold, spring weather is warming, summer weather is hot, and autumn weather is more cooler than summer weather. Furthermore, the scale display the dramatic change in weather temperatures throughout the seasons. Normal human body temperature is 37 degrees Celsius.
If an individual’s body temperature drop to several degrees below 37 degrees Celsius, hypothermia can occur. Additionally, if the body temperature of an individual rise several degrees above 37 degrees Celsius, conditions like heat exhaustion or heat stroke can occur. These temperatures are important to recognize due to the bodys limited ability to compensate for deviations from normal body temperature.
Both scientific and engineering fields use temperature scales in their fields of study. For instance, engineers must know the melting point of metals; however, the metalworking equipment will represent those melting points on a specific temperature scale. Additionally, astronomers represent the vast temperature range in astronomy best on the Kelvin scale.
These scales can be estimated in certain case by using mental calculations and mental math shortcuts. For instance, to estimate the Fahrenheit scale from a Celsius value, double the number and add 30 to the result. To estimate the Celsius scale from the Fahrenheit scale, subtract 30 from the result and divide by two.
Finally, to estimate Kelvin from Celsius, simply add or subtract 273 from the Celsius value. Though each of the scales are arbitrary, each have an important and necessary part in the lives of humans and their understanding of the world around them. The master table allow humans to understand and use the three scales to perform their everyday task.
