The short answer is: Yes, there is, sorta. If you take the ratio of the frequencies of the two pitches, you'll get some fraction in lowest terms. The smaller the numbers in that fraction, the more consonant the interval. For example, two pitches in unison have a 1:1 ratio.

How do you know if a chord is consonant or dissonant?
Chords built only of consonances sound pleasant and "stable"; you can listen to one for a long time without feeling that the music needs to change to a different chord. Notes that are dissonant can sound harsh or unpleasant when played at the same time.
How is consonance and dissonance measured?
As mentioned above, intervals with small number frequency ratios are considered consonances and those with larger or nonconsecutive numbers in their ratios are the imperfect consonances, while those with the largest numbers in their ratios are considered dissonances.
How is math able to predict the consonance or dissonance of musical pitches?
In sixth century BC, Pythagoras discovered the mathematical foundation of musical consonance and dissonance. When auditory frequencies in small-integer ratios are combined, the result is a harmonious perception. ... This result indicates a link between consonance and the dynamical features of the signal.
What is the difference between a consonance and dissonance?
Consonance and dissonance are converse terms and can only be defined in relation to one another. Dissonance is the lack of consonant sounds, and consonance is the lack of dissonant sounds. Dissonance: In music theory, composers use the term “dissonance” to explain why certain melodic intervals feel unresolved.
