Grammar

All senses of conform necessarily involve an underlying comparison of one thing or person to another. To introduce the second thing, there are two acceptable prepositions— to and with —each being more common with certain senses. When the sense has to do with one of the things being the standard or guide for the other, the most usual preposition is to: This wiring does not conform to the building code. The car seat conforms to your body. When the sense has to do with two things that independently happen to agree or match, with is more common: Your observations conform with my own experience. However, in each case, the other preposition is also correct. When the relationship between the two things is not clear, to tends to prevail: Fortunately, the weather conformed to our expectations.

Etymology

Origin of conform

First recorded in 1275–1325; Middle English confo(u)rmen, from Anglo-French, Middle French conformer, from Latin conformāre “to shape, describe, make to agree,” from con- con- + formāre “to shape, fashion” (from forma form )

Explanation

To conform means to adapt to fit in with new conditions. So if you travel to Morocco, you should conform to the local custom and adjust your usual wardrobe to one that is more modest. Sometimes conform gets a bad rap, carrying with it the sense of compromising one’s individuality to fit in or please others. But take note that it doesn’t always have to carry such a negative charge. For example, the manager of a factory that produces bouncy balls would want each ball that came off his conveyor belts to conform to a high standard of durability, bounciness, and roundness.
