Ever wanted to know how many kilometers or miles the lightning is far? Well here’s the answer:

1. Watch the sky for a flash of lightning.
2. Count the number of seconds until you hear the lightning (use a watch for more accurate results).
3. Divide the number of seconds by 3 to know the distance in kilometers and by 5 to know in miles. For example:

• If the time is 30 sec. then the distance in km is 30 divided by 3 equals 10 km
• If the time is 30 sec. then the distance in miles is 30 divided by 5 equals 6 miles

Some people ask why do we need to know this?

The answer is: it is useful for people in countries that lightning occurs every second. Like this they will know if the lightning is near and run away for their lives.

NOTE: This fact is confirmed by many scientists.
