Difference between ほど and まで?


Both seem to indicate an extent of something, but how do they specifically
differ?




〜ほど means "about", "approximately". Similar to 〜くらい.  
〜まで means "until", "by", "till", "reach(まで[届]{とど}く)", "(from something) to
something".

from (something) to (something) means 〜から〜まで

## Examples

>   * それの長さは10メートルほど(=くらい)ある。
>     * Its length is approximately ten meters.
>   * 駅に3時までに着く。
>     * I arrive at the station by three o'clock.
>   * 僕は5時まで学校にいるね。
>     * I'll stay in school until five o'clock.
>   * それはここまである。
>     * It reaches here.
