The difference is that the 4 figure grid map is used for roughly the place that is located in the map while a 6 figure grid is used to find the exact location on the map. So when there's a need to find the exact location use the 6 figure grid instead of the 4 figure grid map.(:
A number is a multiple of 4 if the last 2 digits are a multiple of 4 The 10s digit is even and the last digit is 0, 4 or 8 The 10s digit is odd and the last digit is 2 or 6 A number is a multiple of 8 if the last 3 digits are a multiple of 8 The 100s digit is even and the last 2 digits are a multiple of 8 The 100s digit is odd and the last 2 digits are 4 times an odd number

If your asking in a digit it's called a 4 digit number and it is the smallest 4 digit number
the unit digit is 4
MGR4 (Map Grid Reference, 4) Four Grid Reference
to be able to draw 4 figure grid reference
An area reference is a general location indicated on a map, such as a city or region, while a grid reference is a specific point identified by intersecting lines on a grid system, such as latitude and longitude coordinates or a military grid reference system (MGRS). Essentially, an area reference gives a broader location, while a grid reference pinpoints a precise position within that area.
The disadvantages of four figure grid references are 1 grid reference is 10 2 is 10 3 is 30 and 4 goes to 400..
Area refers to a specific region or area on a map, while grid reference is a system of identifying locations on a map using a grid of horizontal and vertical lines. Grid reference provides a more precise way to pinpoint a location compared to just referring to an area.
say the grid reference was 038441 the four grid referecne would be 0344 which is taking of the 3rd and last number

Because it is much more accurate (long distances) Larger the figures the greater the accuracy- (very accurate)
The difference is that the 4 figure grid map is used for roughly the place that is located in the map while a 6 figure grid is used to find the exact location on the map. So when there's a need to find the exact location use the 6 figure grid instead of the 4 figure grid map.(:
To locate points on the Earth's surface, we can use either rectangular coordinate system or geographic coordinate system.4digit or 6 digit reference systems are under rectangular ( projected) system.Their difference lies in assigning Easting and Northing. 4 digit RS uses 2 Easting numbers and 2Northing numbers to show the location of points where as 6 digit uses 3 Easting and 3 Northing numbers. If there is any Hesitation please Well come.
It is the cell where column D meets row 4.
These are used In grid's. For an example - Grids on A computer - Map's and other. how to use these are VERY Simple. Notice on a map you follow the contor lines's which are the Numbers - Example 1 |_| |_| 2 |_| 3 |@| 4 |_| 5 |_| 6 7 1 2 3 4 5 6 8 9 10 - These numbers are an example, In a map these will go all the way around. Notice the square with the @ symbol in it, the 4 figure grid reference for that is - 43. In normal maps These are in double numbers. like 10. 4-3 - would be 4030, the "4" is the Bottom easting. ( bottom number) that is in that row of squares. and 3 is the HEIGHT. every number like 1-2-3-4-5-6 will Have a row of squares above them. so Tell me the Grid Reference Between 41 ( or 4010) Answer: It is in the "4 " Row, and at the top. of the row. a 6 grid reference Is More presice. these have more numbers than 4- Like 4030 - that cordinate, would have more numbers. Example : ( a 6 figure grid reference is only used to PINPOINT AN exact location of an Object -and the 6 grid reference would be - ( 1 |_| |_| 2 |_| 3 |._| 4 |_| 5 |_| 6 7 1 2 3 4 5 6 8 9 10 I wanna get the location of the Dot It would be "4-7-3-2" - 4 for the coloum, Picture the square from the bottom. was divided into 10' |-|-|-|-|-|-|-|-| you just work how many Lines the Dot is across, which is 7. 4-7. the 3- as the middle row. and the 2 is 2 across. but on the Last 2 numbers. You Work across, on the side go to the LEft or the right side ( left side) and count 10 up from the -->|_| Side notice thr arrow - so it would look like -|- this, this is one side of the square - the left -|- -|- -|- |-|-|-|-|-|-|-|-|-|
