What Is Speed Of Lightning? 

Does lightning travel? Yes, therefore we are going to know the speed of lightning. How is it scary to see lightning and thunder in the sky just before the rain? Ohh! Don’t ask about it. There are lots of people who are afraid of lightning and thunder. They are afraid because lightning has a tendency to fall on the earth by traveling through any medium which is kept at high. There are also different types of lightning, and every lightning has a different speed. Also, it is not easy to calculate the speed of lightning because they travel within a fraction of a second. Let me tell you about the speed of lightning. 

What Is Speed Of Lightning? 

The speed of lightning is 270,000 mph. While he flashes we see a result of a lightning strike traveling at the speed of light which is 670,000,000 mph. What is the speed of a lightning bolt? So, the speed of lightning bolts is about 270 km per hour. 

To understand more clearly, let’s compare the lighting speed with other speeds. The speed of lightning vs light tells us that light is faster than everything and lightning is not light, though it emits some. Also, when you see the speed of lightning vs sound, it will also tell us that lightning is faster than sound. Simply, you see lightning before you hear thunder because light, which travels a million times faster than sound, arrives almost instantly. 

The speed of sound lightning is 1088 feet per second while the speed of lightning in km per hour is 270 km/hr. The speed of lightning in seconds is 186,000 miles per second while the speed of lightning in m/s is 300,000,000 m/s.  

Well, you know the exact speed of lightning mph and also the speed of lightning m/s. Let’s know how to calculate it.

Calculate The Speed Of Lightning 

So, to calculate the speed of lightning you should know the formula which is given by, 

Speed = Distance/Time 

In symbolic form, 

S = D/T


            S is the speed of lightning 

            D is the distance traveled by lightning, and 

            T is the time taken to travel a total distance 

For example, 

Calculate the speed of lightning, if it traveled 1200 km in 2 min. 

So, speed of lightning = 120000 x 2/60 = 4000 km/h  

About Lightning

Lightning is created as a result of an extremely high voltage that is created between the sky and the surface of the Earth. Note that the Earth is, in and of itself, an enormous conductive sphere composed mostly of iron. In other words, lightning is an occurrence of natural electrical discharge of very short duration and high voltage between a cloud and the ground or within a cloud, accompanied by a bright flash and typically also thunder. 

In the early stages of development, air acts as an insulator between the positive and negative charges in the cloud and between the cloud and the ground. 

There are so many facts about lightning and lightning facts for kids. Like helicopters cause lightning, lightning strikes a beach, lightning destroys trees, 1,400,000 strikes every year, and the facts for kids are intracloud lightning occurs within one cloud, cloud to cloud lightning occurs between two or more clouds.   

Here are some facts about thunder and lightning, including 

  • Lightning kills more people every year than tornadoes 
  • If you can hear thunder, lightning is nearby, 
  • You can hear thunder up to 5 miles away, and 
  • When lightning strikes it makes a hole in the air called a channel.

How Fast Is Lightning In KM?

A lightning bolts travel at the speed of light, which is 186,291 miles per second (~300,000 km/s).

What’s Faster Than Lightning?

The answer is Tachyons. They are super-charged particles that travel faster than the speed of light.

Is Lightning Faster Than Sound?

Lightning and thunder happen at the same time. But you see lightning before you hear thunder because light, which travels a million times faster than sound, arrives almost instantly. Sound, on the other hand, takes about five seconds to travel one mile.

What Is Stronger Lightning Or Light?

In real world physics, light beats out lightning in any category in term of strength, destructive power, and speed.

Is A Car Safe During Lightning?

Like trees, houses, and people, anything outside is at risk of being struck by lightning when thunderstorms are in the area, including cars. The good news though is that the outer metal shell of hard-topped metal vehicles does provide protection to those inside a vehicle with the windows closed.

Which Is Faster Lightning Or Electricity?

In copper, electricity travels at about 1/3 the speed of light. Lightning advances much slower than that.

How Many Machs Is The Speed Of Lightning?

The flash from the lighting that we see moves at the speed of light itself. However, the actual strike itself moves at only 1/3 of lighting, 270,000 mph or Mach 364.

Is Lightning Hotter Than Lava?

Lightning is hot. Really hot. It can reach temperatures as high as 50,000 degrees Fahrenheit, five times hotter than the surface of the sun, and even hotter than lava here on Earth.


While reading this article, you learned about the speed of lightning and also you got a formula to calculate the speed of lightning. Lightning is nothing but an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. When the opposite charges build up enough, this insulating capacity of the air breaks down and there is a rapid discharge of electricity that we know as lightning. Mostly lightning occurs within the clouds. Sheet lightning describes a distant bolt that lights up an elite cloud base. This was all about the speed of lightning
