What is the difference between "at least two hours" and "approximately two hours"?

"At least two hours" indicates a minimum duration, whereas "approximately two hours" suggests an estimated duration that could be slightly more or less. The former sets a lower bound, while the latter offers an estimation without a firm boundary.
