To calculate Rt/R25 at temperatures other than those listed in the table, use the
following equation:

To calculate Rt/R25 at temperatures other than those listed in
the table, use the following equation:
Rt/R25 = exp{A + B/T + C/T2 + D/T3}
where T = temperature in K

To calculate Rt/R25 at temperatures other than those listed in
the table, use the following equation:
Rt/R25 = exp{A + B/T + C/T2 + D/T3}
