When You'll Use This
Planning a MOC
Look up your target scale, convert real-world dimensions to studs, and know exactly how many bricks you need before you start.

"Is this 6-wide or 8-wide?" Now you have the math. 6-wide is ~1:45. 8-wide is ~1:30. Done.
Mixing Sets in a Display
Speed Champions next to a modular? Check the scales - they're close enough at 1:30 vs 1:38, but your Technic car at 1:10 will look like a monster truck.
