Is 10 dimes 1 dollar?

Excuse me, I'm just trying to clarify something about basic currency conversion. Is it accurate to say that 10 dimes make up 1 dollar? I've heard conflicting information and I'm hoping to get a definitive answer. In the United States currency system, do the dimes add up to equal a dollar, or am I misunderstanding the relationship between the two denominations? Thank you for your help in clearing this up.
