Extent
An Extent
noun
The kanji and the word are exactly the same. That means they share meanings as well.
You'll see 程 used in all kinds of ways to express the extent or degree of something, like 思った程じゃない (not as much as I expected), 言葉で表せない程すごい (so amazing it can't be expressed in words), or 30分程歩く (to walk for about thirty minutes). Just keep in mind this word is often written in kana.
You'll remember this kanji to the extent that you study it. If you study it like Hodor (ほど) would study it, you won't learn it at all. You would only be able to say "hodor, hodor," over and over again, which isn't helpful at all.
