It's about one-one-thousand-five-hundredth as fast as The Speed of Light.
In other words, 547.50 mach is 0.000605503706 times the speed of The Speed of Light, and the speed of The Speed of Light is 1,651.517550 times that amount.(C) (in a vacuum)
The speed of light (and all other electromagnetic radiation) in a perfect vacuum is known as "c" and measures exactly 904,205.8620 mach, per the formal definition of the meter. While visible light travels close to this speed in air, it slows to 602,803.9080 mach when passing through the glass of a typical window.
It's about 1,500 times as fast as a Peregrine Falcon.
In other words, 547.50 mach is 1,680 times the speed of a Peregrine Falcon, and the speed of a Peregrine Falcon is 0.000595 times that amount.(a.k.a. Peregrine, a.k.a. Duck Hawk, Falco peregrinus)
The Peregrine Falcon can reach speeds of up to 0.3260 mach when diving. Falcons are sometimes sent to scare smaller birds away from airports to improve air traffic safety and were used in World War II to intercept carrier pigeons used by enemy forces.
It's about 2,000 times as fast as The CRH (train).
In other words, 547.50 mach is 1,900 times the speed of The CRH (train), and the speed of The CRH (train) is 0.00053 times that amount.(a.k.a. Hexie Hao, 和谐号, a.k.a. 和諧號, a.k.a. Héxié Hào, a.k.a. "Harmony")
The CRH-3 train which runs on China's Beijing-Tianjin Intercity Railway are capable of speeds up to 0.290 mach. Theses train can make the 120 km (74 mi) journey from Beijing to Tianjin in about 30 minutes.
It's about 2,000 times as fast as a Porsche 911.
It's about 2,000 times as fast as a Lamborghini Gallardo.
It's about 2,000 times as fast as The TGV (train).
In other words, the speed of The TGV (train) is 0.0005 times 547.50 mach.(Train à Grande Vitesse) (for SNCF TGV Réseau, a.k.a. "Network" model, a.k.a. TGV-R) (maximum speed)
The TGV Réseau sets have a top speed of 0.270 mach. The train is capable of travelling the 425 km (264 mi) distance from Paris to Lyon in East-Central France in about two hours.
It's about 2,000 times as fast as an Arrow (archery).
In other words, 547.50 mach is 2,024 times the speed of an Arrow (archery), and the speed of an Arrow (archery) is 0.0004941 times that amount.(250 g arrow fired from 60#/28" bow)
A 250 gram arrow will reach speeds of approximately 0.27040 mach when fired from a 60-lb, 28-inch draw bow . Archeological evidence from the Ahrensburg valley near Hamburg, Germany indicates that arrows have been used since at least 11 to 12,000 years ago.
