Fahrenheit to Celsius Calculator
Convert Fahrenheit readings into Celsius, Kelvin, and Rankine with presets for cooking, weather, and lab temp checks.
Use the offset field if your thermometer or source reading runs high or low, then compare the adjusted result against a benchmark.

Temperature scales allow a person to measure heats. The different temperature scales uses different number to represent the same amount of heat. Two of the most common temperature scales is the Fahrenheit and Celsius scales.
Each of these scale use different starting point and increments. For instance, the freezing point of water is 32 degrees on the Fahrenheit scale, but 0 degrees on the Celsius scale. Additionally, the boiling point of water are 212 degrees on the Fahrenheit scale, but 100 degrees on the Celsius scale.
Temperature Scales and How to Convert
Thus, each of these scale indicates a different rate of movement of heat. To convert from Fahrenheit to Celsius, a person must use a specific formula. The formula state that to convert from Fahrenheit to Celsius, a person must subtract 32 from the number of degree in Fahrenheit, and then multiply that number by 5/9.
A person must first perform these step in this order; otherwise, the degree measurement will be incorrect. Furthermore, a person may need to calibrate the thermometer that they use to measure the temperature. If the thermometer isnt accurate, the reading may need to be adjust before converting to Celsius.
Accuracy in measuring temperature is used in many different environment. For instance, in the kitchen, an oven may reach 350 degrees Fahrenheit, or approximately 177 degrees Celsius. If the incorrect temperature is used in the kitchen, the food may cooked to the wrong temperature.
In the laboratory, different temperature are required for various experiment. For instance, 37 degrees Celsius is the standard temperature for human body heat. If the temperature in the laboratory is incorrect, the experiment may fail.
Additionally, these scale are used for measuring the weather. For instance, 75 degrees Fahrenheit is a pleasant temperature, which is approximately 24 degrees in Celsius. Aside from the Fahrenheit and Celsius scales, other temperature scale exist.
For instance, scientists use the Kelvin scale in scientific work, and start at absolute zero. Additionally, to convert from Celsius to Kelvin, 273.15 is added to the number of degrees in the Celsius measurement. The Rankine scale is similar to the Fahrenheit scale but begin at absolute zero.
While these units of measurement is not used often in everyday life, they are used in the study of science topics like thermodynamics and physics. For instance, a person brewing coffee may desire for the coffee to reach 90 degrees Celsius, which is equivalent to 363 Kelvin. Another factor that can change with the temperature of an object is the environmental factor.
For instance, the boiling point of water change at different altitudes. At high altitude, the boiling point of water is below 100 degrees Celsius. Another environmental factor is that convection oven in the kitchen change the temperature of food different than conventional ovens.
Additionally, humidity affect an individual’s perception of the temperature of there environment. A temperature of 32 degrees Celsius may feel hot to an individual in high humidity, but may be comfortabley to an individual in low humidity. The last topic related to temperature is the rounding of the temperature.
A person can perform rounding a temperature to any number of decimal place, but accuracy and need for precision must dictate the number of decimal place used. For instance, when cooking, rounding to one decimal place may be sufficient. In contrast, two decimal place are required in the laboratory.
Finally, for weather reports, temperature are typically rounded to zero decimal places. By using these method for rounding temperatures, individual can ensure that the temperature to be use in a specific task or environment is accurate.
