Hi there,

I am just confused about the following issue:
when I called someone and then he asked me to call him later! What is the right to say
“I will call you two hours later”
Or
“I will call you after two hours”

thanks in advance,
Audry

I suggest:
I will call you in two hours.
or
I will call you in two hours’ time.
If you mean you will call sometime after two hours have passed, then I suggest:
I will leave it at least two hours until I call you.

So according to your explanation, Madam BN.
I’ll call you after two hours. Means I’ll call you after two hours have passed but it may be after 2 hours and 30 minutes.
I’ll call you in two hours. Means I’ll call you as soon as two hours have passed. Right?
Many thanks.

yes.
(In the case of the latter, it may not be exactly 2 hours, but it will be close to that time.)

It is simplest to say, if you want to use ‘later’ in your comment :

I’ll call you later in about two hours’ time
