(UK-US English) If "mom = mother" then why "mum" isn't "muther"?

So, I've noticed something weird. People who speak US English say Mom. Mom represents the word "mother".

People who speak UK English say Mum. Mum also represents the word "mother". Why isn't it "muther"?

Is it just the way "mum" is spelled correctly in UK English or I'm really onto something here?

I know it wouldn't make any sense, I'm just wondering why is that so.
