Ludwig's WRAP-UP

The phrase "proportionally with" serves to indicate a relationship where two quantities vary in a consistent ratio. As Ludwig AI confirms, it is grammatically correct and sees frequent use in a variety of writing contexts, especially in scientific and technical domains.

Overuse in contexts without a clear, direct correlation should be avoided to maintain precision. As examples within Ludwig suggest, this phrase is frequently used to describe physical, chemical, and even economic relationships.
