Goku is a fictional character from the Dragon Ball series, and as such, he does not have an actual speed in miles per hour (mph). However, there are various instances throughout the series where his speed is mentioned or shown, and it can be estimated based on those references.
In the Dragon Ball universe, characters often measure their power levels, which are a representation of their strength and speed. Goku’s power level increases throughout the series, and at one point, he is said to have a power level of 3,000. Based on the assumption that a power level of 5 corresponds to a speed of 60 mph, it can be estimated that Goku’s speed at a power level of 3,000 would be around 36,000 mph.
Another instance where Goku’s speed is referenced is during his fight with Beerus in Dragon Ball Super. Beerus is said to have the ability to move at the speed of light, and during the fight, Goku is shown to be able to keep up with him. Based on the fact that the speed of light is approximately 186,282 miles per second, it can be estimated that Goku’s speed in this instance would be around 671,000,000 mph.
It is worth noting that Goku’s speed is often depicted as much faster than what is considered possible by the laws of physics. In the Dragon Ball universe, characters are able to move at superhuman speeds and even travel through space without the need for spaceships or other technology. As such, any attempts to estimate Goku’s speed in real-world terms should be taken with a grain of salt, as the rules of physics do not necessarily apply to the Dragon Ball universe.
In conclusion, Goku’s speed in miles per hour is not a fixed value, as it varies depending on the specific instance in the Dragon Ball series. However, based on references to his power level and ability to keep up with Beerus, it can be estimated that his speed ranges from around 36,000 mph to over 671,000,000 mph. It is important to note, however, that these estimates are based on fictional events and should not be taken as representative of real-world physics.
