Count the seconds from flash to first rumble, and divide by 5: that's the distance in miles.

Lightning travels at 186,000 miles per second so you will see that instantaneously. Thunder travels at about 1,200 feet per second (depending on air temperature) so there will be a delay between when you see the lightning and hear the thunder. To calculate how far away the lightning is starting counting as soon as you see the lightning. Count>one onethousand, two onethousand, threeonethousand and so on...... For every 5 seconds that you are able to count before hearing the thunder, the lightning is 1 mile away.

The conversion is 5 seconds for one mile, which is a close approxmiation to the speed of sound.
