How do you convert DD.MM.SS to DDMM.mmmmH lat.? DDD.MM.SS to DDDMM.mmmmH

Thanks much

To convert your lat/long from decimal degrees like DD.dddddd just use the 2 digits (for the first number, 3 for the second) before the decimal, then multiply the .dddddd by 60, and put that after the DD with 2 digits, decimal, then 4 digits after the decimal.? So 12.3456 degrees as latitude?becomes 1220.7360

To convert DD MM SS to DDMM.mmmm, use the 2 DD digits (3 for longitude), then 2 MM digits, then decimal/period, the divide SS by 60 (it should?be less than 1) and use the 4 digits after the decimal, padded with 0s if needed.? So 12 degrees 34 minutes 51 seconds as a longitude becomes 01234.8500

You always have 4 digits for latitude or 5 digits for longitude before the decimal, and 4 digits after the decimal, then the direction letter.

North is positive - South negative.

East is positive - West negative.

This is always easiest to explain with a fill example, so if you post information you want translated, we can use it as the example and provide the information in a way that you will be able to use in the future.

another good one is here

Totally confused now.

What EXACTLY are you trying to do - set the LOCATION in the TT4?

If so, the manually is quite clear:

LOCATION [ DDMM.mmmmH DDDMM.mmmmH ]

Sets the initial default latitude and longitude in degrees and minutes. This value will be
used in position reports until overridden by incoming GPS data. TOSV must be set to
false to report this setting. Format must match exactly, including number of digits after
the decimal point. For example: to set to 34° 45.29’ North, 76° 13.7482’ East, use
“LOCATION 3445.2900N 07613.7482E”.
