I happened to have an OS map for the area and I used Google Maps to find out where Aislaby was - once I had located Aislaby on the map, I could work out what grid square was needed. It's not exactly a quick process though!
I know womble's post was over a year ago, but her's a tip:
http://www.streetmap.co.ukSearch the place, e.g. Aislaby and bring the map up
Find a link near the map called "Click here to convert and measure coordinates" or similar
It will give the grid ref of Aislaby, which would be NZxxxyyy....
The NZ is a square number from a grid covering the UK:
A grid ref of NZ 111 222 could also be written as a full reference of
411100,522200 and is a literal number of metres in a
east,north direction from a point off the tip of lands end in cornwall.. so essentially the NZ is the
4 and the
5 in the fullgrid ref (because NZ is 4 along and 5 up, remember to count square SV as 0,0), and then the 11100 is that number of metres east into square NZ (which starts
400000 metres east,
500000 metres north of cornwall) and 22200 is the metres north from the start of the square. You can specify any number of digits you like in the grid ref but in NZ 111 222 form it's accurate to 100metres, in full 6 digits per coordinate form it's accurate to 1 metre
