Both Netflix and IMDb obtain user ratings on a whole number scale; Netflix users score movies on a 1-5 scale, while IMDb users grade on a 1-10 scale. So you might naively conclude that, aside from the degree of uncertainty, a Netflix average user score of 3.7 is equivalent to an IMDb rating of 7.4 – but that would be wrong! Use this JavaScript-based movie rating conversion form to calculate the equivalent rating of either type to a score on a 1-99 scale.
