Can anyone give me the answers to these questions please

400 p for m in m
1 h on a d
1 fs
18 a of kt at d

Please check out the following links:

"400 p for m in m" - Google Search

"1 h on a d" - Google Search

I didn't find anything for the "1 fs" or "18 a of kt at d.'

But, someone might still come up with an answer, though.
