Is there a way to format time in variable units?

I would like to be able to format a time value so that it is displayed in the smallest units that are less than "1" of the next larger unit. That is, use seconds up to 1 minute, then minutes up to 1 hour, hours up to 1 day, etc. I would also like to be able to specify the number of decimal points to display, which complicates things.

Here are some examples:

I started writing a UDF, but it quickly got complicated. Is there an easy way to do this?

If not, I'll post my UDF if I ever get it working.
 
The following UDF returns the expected results for the dataset from Post # 1:
Code:
Public Function FmtTime(ByVal pTime As Double, _
                Optional ByVal pInUnits As String = "Days", _
                Optional ByVal pDP As Byte = 1, _
                Optional ByVal pNegOK As Boolean = False) As String
    If pTime < 0 And Not pNegOK Then FmtTime = CVErr(xlErrValue): Exit Function
    prf = Sgn(pTime)
    pTime = Round(Abs(pTime), pDP)
    Select Case Left(UCase(pInUnits), 1)
        Case "S": curr = " secs": thr = 60: nxt = " mins"
        Case "M": curr = " mins": thr = 60: nxt = " hours"
        Case "H": curr = " hours": thr = 24: nxt = " days"
        Case "D": curr = " days": thr = 30: nxt = " months"
    End Select
    If pTime < thr Then
        FmtTime = prf * pTime & curr
    Else
        FmtTime = prf * Round(pTime / thr, pDP) & nxt
    End If
End Function

Excel Facts

What does custom number format of ;;; mean?
Three semi-colons will hide the value in the cell. Although most people use white font instead.
i tried using formula

Code:
Value	Units	DP	Result       	using formula
1.75	sec	0	2 secs       	2 secs
1.75	sec	1	1.8 secs	1.8 secs
59.49	sec	1	59.5 secs	59.5 secs
59.5	sec	1	59.5 secs	59.5 secs
59.5	sec	0	1 mins       	1 mins
59.95	sec	2	59.95 secs	59.95 secs
59.95	sec	1	1 mins      	1 mins
23.49	hour	1	23.5 hours	23.5 hours
23.49	hour	0	23 hours	23 hours

200.5	sec	0      	        	3 mins
61.7	sec	1       		1 mins
12.6	hour	1              		12.6 hours
25.6	hour	1               	1.1 days
30.2	hour	1              		1.3 days
180.2	sec	1              		3 mins
98	sec	10	        	1.6333333333 mins
101.5	hour	5	         	4.22917 days
76.367	hour	17	        	3.18195833333333 days
42	hour	4	        	1.75 days
140.777	sec	2	        	2.35 mins


cell under "using formula" column is
Code:
=IF(B2="sec",(IF(QUOTIENT(ROUND(A2,C2),60)<1, ROUND(A2,C2)&" secs",QUOTIENT(ROUNDUP(A2,C2),60)+IF(ROUND(MOD(A2,60)/60,C2)<1,ROUND(MOD(A2,60)/60,C2),0)&" mins")),IF(B2="min",IF(QUOTIENT(ROUND(A2,C2),60)<1, ROUND(A2,C2)&" mins",QUOTIENT(ROUNDUP(A2,C2),60)+IF(ROUND(MOD(A2,60)/60,C2)<1,ROUND(MOD(A2,60)/60,C2),0)&" hours"),IF(B2="hour",IF(QUOTIENT(ROUND(A2,C2),24)<1, ROUND(A2,C2)&" hours",QUOTIENT(ROUNDUP(A2,C2),24)+IF(ROUND(MOD(A2,24)/24,C2)<1,ROUND(MOD(A2,24)/24,C2),0)&" days"))))

this doesnt account for units in days though

Thanks to everyone for their comments. Unless I made a mistake, the code form both Mike E and Tetra have bugs related to rounding. I believe the problem is that they round before converting the units. Based on all of this, I completed my UDF, which I have posted below. Here are the results of the sample data for the three solutions:

Here's my code. Comments appreciated.

ok - not exactly the prettiest solution, but tell me what you think about this:
cell E2:
Code:
=IF(B2="sec",A2,IF(B2="min",A2*60,IF(B2="hour",A2*60*60,IF(B2="day",A2*60*60*24,IF(B2="week",A2*60*60*24*7,IF(B2="month",A2*60*60*24*7*30,IF(B2="year",A2*60*60*24*7*30*12,0)))))))

cell F2:
Code:
=IF(ROUND(E2,C2)<60,"sec",IF(ROUND(E2,C2)<3600,"min",IF(ROUND(E2,C2)<86400,"hour",IF(ROUND(E2,C2)<604800,"day",IF(ROUND(E2,C2)<2592000,"week",IF(ROUND(E2,C2)<31104000,"month","year"))))))

cell G2:
Code:
=ROUND(IF(F2="sec",E2,IF(F2="min",E2/60,IF(F2="hour",E2/3600,IF(F2="day",E2/86400,IF(F2="week",E2/604800,IF(F2="month",E2/2592000,E2/31104000)))))),C2)&" "&F2

then hide columns E & F?

Thanks, Mike, but I really want a UDF solution. Even if the cell formula works, I have to remember it and copy it without making a mistake. It's just too messy. :eeek:
