A windshield survey data collection grid is a tool used to systematically collect data while conducting a windshield survey. It is essentially a table or grid that includes different categories or attributes that need to be observed and documented during the survey. The grid helps to organize and record information such as physical features, social and economic factors, and community resources observed from the car window.
Take a look at this Ordanance Survey page. http://benchmarks.ordnancesurvey.co.uk/pls/htmldb/f?p=111:7:6255072357299077241::NO:7:: Type in a kilometer square grid in the form "SP9013" for instance. This page will give you a conversion factor. It seems a little ambiguous as to whether the figure they give you is to convert Newlyn to Liverpool or vica versa. I am still investigating.

A six figure grid co-ordinate system is the standard method for maps. This system is used in the Global Positioning System.
It goes from the North Pole to the South Pole through the Royal Observatory, Greenwich.
it means ......The Ordnance Survey National Grid reference system is a system of geographic grid references used in Great Britain, different from using latitude and longitude.
You can find Ordnance Survey maps and products on their official website, at outdoor and map retailers, or at some tourism information centers in the UK. Additionally, some libraries may also have copies of Ordnance Survey maps for reference.
The global grid helps me see where the prime merdian is
Go to the Ordnance Survey website (UK) and information on using a 6 figure grid reference can be found there. Basically, the UK is covered in 100,000 metre grid squares. Each grid square is identified by two letters. These squares are further divided into 10,000 metre squares that are numbered along the map's borders. An example reference could be: SD 638365 The SD identifies the 100,000 metre square, the 63 is the vertical line to the west of the point. The 8 is the tenths from that line easterly to the point. The 36 is the horizontal line south of the point. The 5 is tenths northerly from the line to the point. (5 would be half way). Instructions on taking grid references are printed on all Ordnance Survey Maps.
Ordnance survey maps are maps that show altitude in relation to a 'known' ordnance datum. An ordnance datum is a point of particular altitude. In the UK, that ordnance datum for ordnance survey maps is the mean sea level at Newlyn in Cornwall. Ordnance survey maps typically show topography, by means of contour lines and spot heights. General land detail, such as grass-land, forest, marsh. In addition roadways, railways, footpaths and bridleways are shown. This makes ordnance survey maps of particular use for anyone wishing to navigate on foot. And this remains one of the most popular uses for this type of map.

No
You should find the answer on the ordnance survey website: http://www.ordnancesurvey.co.uk/oswebsite/gi/nationalgrid/nghelp1.html In essence the first two digits of X and Y correspond to a grid of alphabetical references, giving you the first two letters of the BNG. Hope this helps.

Grids are used to identify specific locations on a map by dividing the map into smaller sections. Each grid square is assigned a unique reference, such as coordinates or letters and numbers, making it easier to pinpoint a specific place. Grids are commonly used in cartography and navigation to provide clear and precise location information.
The definition of global grid is a grid that covers the whole Earth.
