Yes!!!!
The measurements must be equal to each other.
Time
Could be the conversion factor - but only if the two sets of measurements are on scales that are linear AND absolute.
proportion
If the two measurements are of the same type, such as length, we could use that ratio to convert from one measurements to another. An example is the ratio of 1.609 Km to 1 mile. Here, we can multiply some number of miles by 1.609 and find the kilometer distance. If the two measurements are of different types, that is often used as a definition of another quantity such as speed. Speed is defined as the ratio of the distance traveled to the amount of time it takes. These two examples are the most common uses when taking the ratio of two measurements, yet there may be a more generalized term or theorem here, but I've not heard of it yet.

The measurements must be equal to each other.
The circumference of a circle divided by its diameter is equal to pi.
Rate
Time
Cross Products is the ratio between two sets of measurements.
There is no real reason for two equivalent measurements to be rationed! The ratio of two equivalent measurements will depend on the units used. The ratio between a length in feet and the equivalent length in inches, for example, is 12:1.

Possibly the conversion factor.
