Measured against the length of a table-tennis table, 509 centimetres spans about 1.9 times that reference.
Its published measurement is 274 centimetres; the ratio is calculated from that figure.
Measured against the typical upper length of an adult blue whale, 509 centimetres spans about 17% of that reference.
Using the source measurement of 3,000 centimetres, this comparison puts the target at 17% of it.

509 centimetres is approximately 200.4 inches.
Using the exact conversion that 1 centimetre equals exactly 0.3937007874 inches, the unrounded result is 200.394 inches.
Reference measurements are rounded where appropriate, and naturally variable objects are described as approximate, typical, or maximum sizes.
