An empirical formula has been proposed by Rankine for columns of all lengths. Fahrenhiet=Ra - 459.67. To convert between Fahrenheit and Celsius use this formula: Fahrenheit Temperature = (Celsius Temperature)x(9/5) + 32. Formula to convert temperature from Rankine to others. Rankine is similar to the Kelvin scale in that it starts at absolute zero and 0 °Ra is the same as 0 K but is different as a change of 1 °Ra is the same as a change of 1 °F and not 1 °C . Definition of Reaumur Scale and its uses . It is an empirical formula used for the calculation of ultimate load both for short and long columns. The Rankine (°R) scale is named according Scottish scientist William J.M. Rankin’s formula is also known as Rankin Gordon Formula. Temperature differences on the Rankine scale are identical to differences on the Fahrenheit scale, but absolute zero is given as 0°R. Rankine (°R) = Fahrenheit + 459.67 If required, there are worked examples below which use this formula to show how to convert a temperature in Fahrenheit to a temperature in Rankine. Load coming on that column is 400 N. Critical stress coming on that column is 320×10^2 Newton/meter square. Radius of Gyration can be calculated by using formula; Now, calculate the least moment of inertia. External diameter of a column = D = 24 cm, Internal diameter of a column  = d  = 20 cm, Critical Stress = fc = 320 x 10^6 Newton / sq.meter = 32 KN/sq.meter. A degree Celsius can refer to a specific temperature on the Celsius scale, and can also serve as a unit increment to indicate a temperature interval (which is a difference between two temperatures or an uncertainty). . It is also known as centigrade. Rankine. In order to get safe load, divide ultimate load ( Load obtained from Rankin’s Formula) with factor of safety (F.O.S).eval(ez_write_tag([[300,250],'engineeringintro_com-box-3','ezslot_8',107,'0','0'])); Mathematically, Rankin’s formula can be expressed as; Where,eval(ez_write_tag([[580,400],'engineeringintro_com-medrectangle-3','ezslot_5',108,'0','0'])); fc = Critical Stresseval(ez_write_tag([[300,250],'engineeringintro_com-medrectangle-4','ezslot_0',109,'0','0'])); A = Cross-sectional Area of Columneval(ez_write_tag([[300,250],'engineeringintro_com-box-4','ezslot_3',110,'0','0'])); a = Rankin’s Constant: It depends on the material of column.eval(ez_write_tag([[300,250],'engineeringintro_com-banner-1','ezslot_4',111,'0','0'])); For different materials, vale of “a” are as following; For Mild Steel  = a =  1/7500eval(ez_write_tag([[250,250],'engineeringintro_com-large-leaderboard-2','ezslot_2',112,'0','0'])); A column of a building looks not safe. In this scale, water freezes at 0 degrees and boils at 100 degrees. As for the Kelvin scale, 0 on the Rankine scale corresponds to absolute zero, but the unit increment corresponds to one Fahrenheit degree. The boiling point of water is 100 °C. Kelvin=Ra / 1.8.
