くらい is the most common way of saying “about” or “approximately” in Japanese. It will usually be introduced appended to a counter to let us say “about five minutes” or “about ten dollars”. Either くらい or ぐらい can be used; although when the particle is appended directly to a noun (e.g. a counter) then it will normally be pronounced ぐらい. Incidentally, the kanji is 位, but the hiragana is more often used in writing.
