This report will produce a poster showing the relationship between the temperature scales of Fahrenheit, Celsius and Kelvin using equations and graphs including an evaluation of the usefulness of each.
Temperature Scales
The three different temperature scales used today are Fahrenheit, Celsius and Kelvin.
Fahrenheit (°F)
Fahrenheit temperature scale, developed in 1724 by Gabriel Daniel Fahrenheit, is based on 32 for the freezing point and 212 for the boiling point of water (Three Big Temperature Scales, n. d.). The interval between freezing point and boiling point is divided in 180 equal parts. The absolute zero for the Fahrenheit temperature scale is at -459. 67 °F. It is a non-metric temperature scale. Meteorologists in the United States use it to record surface temperature measurements. Medical practitioners use it to record human body temperature.
Celsius (°C)
Celsius temperature scale, invented in 1742 by the Swedish astronomer Anders Celsius, is the modern system of measuring temperature and is based on 0 for the freezing point and 100 for the boiling point of water. The interval between freezing point and boiling point is divided in 100 equal parts. The absolute zero for the Celsius temperature scale is at -273. 15 °C. It is a metric temperature scale. Both Fahrenheit and Celsius are used to record weather temperatures.
Kelvin (K)
Kelvin temperature scale is an extension of the degree Celsius scale down to absolute zero (Metric system temperature, n. d.). In this scale, water freezes at the value 273. 15 and boils at 373. 15. The absolute zero for the Celsius temperature scale is at 0 K. It is a metric temperature scale and is used in most of science (Units of Temperature, n. d.). Kelvin scale has been adopted as the international standard for scientific temperature measurement.
Fahrenheit to Celsius Conversion
The equation to convert Fahrenheit to Celsius is given by

The above equation is related to the straight line equation, y = mx + c. The value of slope constant, m is 1/1. 8 or 5/9 and the value of intercept constant c is 32/1. 8 or 160/9 = 17. 78.
Fahrenheit to Kelvin Conversion
The equation to convert Fahrenheit to Kelvin is given by

The above equation is related to the straight line equation, y = mx + c. The value of slope constant, m is 1/1. 8 or 5/9 and the value of intercept constant c is 273 + 32/1. 8 or 2617/9 = 290. 78.
Kelvin to Celsius Conversion
The equation to convert Kelvin to Celsius is given by

The above equation is related to the straight line equation, y = mx + c. The value of slope constant, m is 1 and the value of intercept constant c is -273.
Conversion Graph for Fahrenheit to Celsius and Fahrenheit to Kelvin
Figure 1 shows a graph with lines that shows the conversion from Fahrenheit to Celsius (green line) and Fahrenheit to Kelvin (maroon line). As shown in figure 1, both lines are straight line.
