User Guide

This tool will calculate the difference in temperature between two measured temperatures ΔT = T₁-T₂ and will convert any combination of temperature units for each temperature value.

T1 – Temperature

Enter the temperature you want to subtract from here.  This could be the highest temperature when comparing two temperature measurement zones, or the end temperature following a test for an incremental rise or fall in temperature.

T2 – Temperature

Enter the temperature you want to subtract here.  This could be the lowest temperature when comparing two temperature measurement zones, or the start temperature when beginning a test for an incremental rise or fall in temperature.

ΔT – Temperature Differential

This is the difference in temperature between T1 and T2 . If T1 > T2 the difference will be positive (+), and if T1 < T2  the difference will be negative. Since ΔT is not a measured temperature, it is converted to other temperature units using different formulas, see this temperature difference converter for more details on the formulas for converting temperature differences.
