I'm trying to calculate and average using a time frame in the day. I want to use a certain number "X" that correlates to a hour/minute in the current time. How do I write a statement to get me the correct "X" value?

example:


8:00 .005
8:01 .006
8:02 .0075
8:03 .0077
8:04 .008

time now is 8:03

How do I get the .0077 in excel?

thx
