Convert decimal degree (lattitude/longitude) into Degree,

[Tim Ashcom]

Need formulae to convert decimal degree (lattitude/longitude) into Degree,
Minutes, Seconds format.

I have the following:
Lattitude data of 0.1741463938 and to convert to decimal degrees, I muliply
by 180 which gives me decimal degrees of 31.3463508840. Now I need to
convert to a Degree, Minute, Seconds format (N34* 50' 56.04"). Note: the '*'
represents the 'degree' symbol - did not know how to display the symbol.
Need to also display whether 'N' (North) or 'S' (South) based on actual
coordinate.

For Longitude, I have data of -0.4758427618 *180 = -85.6516971240 (decimal
degrees) and need to also convert to Degree, Minute, Seconds format (W16* 40'
23.54"). Note: the '*' represents the 'degree' symbol - did not know how to
display the symbol. Need to also display whether 'W' (West) or 'E' (East)
based on actual coordinate.

The formulae needed will take the original lat/long data, multiplied by 180,
and then ???? applied to deliver the data in Degrees, Minutes, Seconds format.

Thank you very much for your assistance.

I did, but not much help for a novice Excel user. What will help the best is
an exact formula to do the calculations.

Thanks for any additional assistance.

I don't understand your calculations

How are you going from decimal degrees of 31.3463508840 to N34* 50'
56.04"?? Where are the extra degrees coming from?

Seems to me that 31.3+ decimal degrees should yield a DMS of

31°20'46.86"

JE,

The original data comes from a Flight Data Recorder parameter. We have to
multiply the data by 180 to convert to a decimal degree format. Now what I
need is to know how to convert from decimal degree (dd) to degrees, minutes,
and seconds (dd mm' ss").

Thanks,

Tim

That's fine, but there's no way 31.3463508840 decimal degrees converts
to N34°50' 56.04" without adding or multiplying by another factor.

31 decimal degrees will convert to 31 degrees in DMS format, too.

Again, to convert to 31°20' 46.86", just follow Chip's instructions:
Divide by 24 and format using the custom format [hh]°mm'ss\"
