All the others are out to more decimal places. Are you sure these are the numbers you want calculated. Just asking before I give it a go.

Someone please double check me. I did these BF (before coffee) which is always a risky proposition.

Deral!!!!!
Thank you VERY much. I owe you bigtime.
Of course when I return home I will check all
Of the coords for him but now at least he can
Get his preliminary boring plots done.

I have only an iPhone with me so I can't practically
Check his other coords.

Thanks again. Much.

The favor you did was so a repeat client's drafter
Could work this weekend and at least start.
I will check and recheck and personally certify
The numbers when I return Wednesday.

MERRY CHRISTMAS. THANKS

Frank
From my iPhone

Okay, is that Northing in French Feet or GIS Feet?

62934.700m = 206,478,2616 GIS Feet?

Good catch Kent. The period and the comma look the same before you have a cup of coffee in the morning.

Hope you noticed that also Frank.

Quesiton for Frank

Why is there a 15 after every " except for the one you requested? Is this pure coincidence?

Deral matches what I get from Corpscon within 0.001 ft, AFTER I remember to remove the degree, min, sec punctuation.

Dang, that program needs to complain if it is going to get indigestion on your entry, instead of giving you some semi-reasonable looking wrong answer.

HC,
The 15 is the UTM zone.

Deral, I checked yours, and it is exactly what I got. I went ahead and recalculated all of the ones the guy had sent me in UTM meters, and they were all off.

THANKS AGAIN!!!!
