How Does It Work?

12

Grid Zone Designation (6 x 8 Degrees)

USNG format: 15T VK 9193 7797

100,000 Meter (100 KM) Squares

USNG format: 15T VK 9193 7797

VK

10,000 Meter Squares (10 KM - repeat about every 62 miles)

USNG:15T VK 97

So USNG format: VK 9193 7797

Can become: 9193 7797 for response purposes!
