What is the association between a comet size and its crater diameter approximately?

Are you asking how big the crater would be if it struck the Earth? In one sense, it would depend on the size of the comet and the speed; in another sense, it might not matter at all.
The kinetic energy of any object is the mass times the velocity squared. Calculate the approximate mass of the comet, multiply it by the collision speed. If the comet were to come from behind, the impact velocity would be lower than if the comet hit us "head on". Whatever the comet's velocity, you would need to add the Earth's escape velocity; any object falling to Earth from space will have a additional velocity from Earth's gravity, which is 7 miles per second, about 25,000 miles per hour.
Here's why it really wouldn't matter; if the comet is big enough and fast enough, it won't create a crater; it will re-make the Earth itself. The comet could punch THROUGH the crust of the planet, releasing the magma, the liquid rock in the mantle. If it's big enough, it could wipe out humanity, and many other species on Earth.

Does mt fuji have a crater?
What is the diameter of Mt. Fuji's crater
What is the crater diameter of mt vesuvius?
The diameter of Mount Vesuvius is 6 kilometres.
How does the kinetic energy of an impacting object relate to crater diameter?
You can't, as you don't know the viscosity of the object it is hitting.
Los is a small crater located on what neighboring red planet?
Los is a small crater located on Mars. The crater was named for a Swedish place name and is 7.9 kilometers in diameter, having been approved as a crater in 1979.
What effect will a 65ft diameter asteroid have on earth if it does hit the earth?
It will create a crater similar to the Barringer crater (Meteor crater).Where it actually hits will determine the overall destructive effect.Oceans: TsunamiCities: Total destruction.Barren land: Crater.
How long is the crater Mexico?
You mean the Chicxulub crater, which is connected with the extinction of dinosaurs? It has a diameter of approximately 180 kilometers (112 miles).
Where is the crater that is evidence of the meteorite impact that ended the Mesozoic?
The Chicxulub impact crater in the Gulf of Mexico is the most likely suspect for the meteorite impact that caused the Mesozoic extinction. The crater is 180 km in diameter, suggesting that the impacting body was approximately 10 km in diameter.
How deep is Meteor Crater?
There is no normal diameter of a meteor crater. They all vary in size depending on the size of the meteorite. Many are between 10,000 and 30,000 meters in diameter but some can but much larger.

Are there craters on both the earth and moon?
Yes. both the moon and the earth has several craters from meteorites. The most known/largest crater on the earth is the "Barringer Crater" in Arizona which is over a kilometer in diameter and approximately 40'000 years old
How big is the Barringer Crater?
It is 0.737 miles in diameter.
How wide is Arizona meteor crater?
Arizona meteor crater is 0.737 miles or 1.186 kilometers in diameter.
How big is the crater the took out the dinosaurs?
A crater did not take out the dinosaurs..... But the crater caused by the asteroid that took out the dinosaurs is about 180 km (110 miles) in diameter.
How does the kinetic energy of an impacting object relate to crater diameter?
You can't, as you don't know the viscosity of the object it is hitting.
