Is there a possibility to do 10 different coordinates at once?

You do need to include the first 2 letters. It can then be a 4, 6, 8 or 10 digit reference number (separated with a space)

do you have to include Map letters e.g SU? do you write 3,4 or 5 figure grid reference?

Brilliant!! I have to drive to a car park at the start of a NT walk which gave only grid ref. This genius idea is EXACTLY what I needed. Many,many thanks.

Worked well for me.

Absolutely brilliant, thank you. Works every time whilst other on-line conversion packages don't always. You just need to substitute the first number of the full 6 figure OS reference with the appropriate OS prefix letter used to name 1/2500 OS plans. Eg 400000 500000 = NZ. Hence 419940 552750 becomes NZ 19940 52750 for the purposes of converting to the post code.
