How convert 6 figure grid into 4 figure grid? - Answers

To convert a 6-figure grid reference into a 4-figure grid reference, you need to round the first two figures of the eastings and the northings down to the nearest ten. For example, if the 6-figure reference is 123456, the eastings would be rounded to 123400 and the northings to 456000, resulting in a 4-figure grid reference of 1234 4560. This method provides a less precise location but is useful for broader navigation.
