Expressing that one action or state increases or changes in proportion to another.
A conditional pattern meaning 'the more A, the more B'. Repeat the same verb or adjective in the conditional form and add ほど.

Indicating that an action or state reaches such a degree that a particular result occurs.
Used with nouns or verbs to mean 'so A that B', often with a negative or extreme result. A is the cause, B is the result.
I was so happy that I burst into tears.
I was so nervous that I couldn't get the words out.
Expresses that A is to the extent that B happens. Often used in casual speech. Can be replaced with ぐらい.
I'm so happy I could cry.
Also used for resultative extent, similar to くらい. Indicates that A is so extreme that B occurs.
Expressing that something is true only to a certain degree or within certain limits.
Means 'as long as A, B' or 'to the extent that A, B'. Indicates a condition or limit.

Means 'to the extent that A, B' or 'as much as A, B'. Often used with verbs of ability or knowledge.

Both ほど and くらい can express extent, but ほど often implies a higher degree or a limit, while くらい is more neutral and often used for approximations. In negative sentences, ほど is preferred for comparisons (e.g., 思ったほど難しくない 'not as difficult as I thought').
I'm so tired I could die. (emphasizing extreme degree)
I'm so happy I could cry. (more neutral extent)
Avoid directly translating 'to the extent that' word-for-word. Japanese uses specific grammatical patterns like ほど, くらい, ば...ほど, etc. Using 程度 (ていど) is possible but often sounds stiff or overly formal in casual contexts.
I walked so much that my feet hurt.
It was surprisingly easy (to the extent that I was surprised).
できるだけ早く来てください。
Please come as soon as possible (to the extent that you can).
