Converting the other way: millimeters to yards
yards = millimeters × 0.00109361. So 274,320 millimeters is back to 300 yards; one millimeter is 0.00109361 yards. See the millimeters to yards table.
Quick estimate in your head
For a rough answer, multiply by about 900: 300 × 900 ≈ 270,000 mm, against the exact 274,320 mm (1.6% out). Good enough to check that a calculated result is sensible.
Common mistakes
The usual slip is using the factor the wrong way round. A yard is bigger than a millimeter, so the number of millimeters must come out larger than the number of yards. If your answer goes the other way, divide instead of multiplying.
