WebbDelta H Formula: The change in enthalpy can be quickly calculated in a given thermodynamic system that has undergone a chemical reaction by the following formula: ∆H = cm∆T. Where ∆H refers to change in enthalpy of a reaction, C refers to the specific heat. It is constant for all substances, m represents the mass and, WebbCalculator Use. Temperature conversions are performed by using a formula, which differs depending on the two temperature scales you are converting between. For example, to convert 50 degrees Celsius (centigrade) to Fahrenheit, we plug our numbers into the formula as shown below: °F = °C * 9/5 + 32. °F = 50 * 9/5 + 32. °F = 90 + 32.
