Time difference Δ t and sound path distance or lenght d
Conversion: Running time to milliseconds or microseconds ←→ sound path to meters, cm, feet or inches
The acoustic time of the travelling sound is converted to distance or the distance is converted to time

Notice: 1 second (s) = 1000 milliseconds (ms) und 0.001 second (s) = 1 millisecond (ms).
1 millisecond (ms) = 1000 microseconds (µs).

distance in meters (m) 

 time difference in  seconds: 
centimeters (cm)  = seconds 
feet (ft)  + milliseconds 
inches (") Zoll  + microseconds 
For the speed of sound of c = m / s ft / s
Fill in the gray fields above, select the unit and click on the calculation button of the respective
column. Also the adjusted speed of sound can be changed: 343 m/s or 1125.33 ft/s at 20°C. When
converting seconds to distance, the seconds have to be multiplied by 1000 and entered in the first
field with the unit ms. The well known maximum value of the time difference from ear to ear is
0.63 ms - and the beloved "ear distance" that is believed to be 0.175 m = 17.5 cm.
Really? Do a calculation.
