speeds like mph are distance divided by time. So divide 100 meters by the dash time to get a speed. Then convert units to miles per hour. Or convert before you divide, meters to miles and dash time to hours.

To convert a 100 meter dash time into mph, you would first need to convert the time into seconds. Then, divide 100 meters by the time in seconds to get the speed in meters per second. Finally, convert meters per second to mph by multiplying by 2.237.
To convert a time in a 100m dash to miles per hour (mph), you can use the formula: mph = 3600 / (time in seconds). If the time in the 100m dash is 13.00 seconds, then the calculation would be: 3600 / 13.00 = 276.92 mph.
it would depend on how hot or cold it is.
The current world record for the men's 200m dash is 19.19 seconds, set by Usain Bolt in 2009, and for women, it is 21.34 seconds, set by Florence Griffith-Joyner in 1988.
To convert swim times from meters to yards, you can use the conversion factor of 1.0936 (1 meter is approximately equal to 1.0936 yards). Simply multiply the swim time in meters by this conversion factor to get the equivalent time in yards. For example, if a swimmer completes a 100m race in 1 minute, the equivalent time in yards would be approximately 1 minute and 5.47 seconds (1 minute * 1.0936).
The prefix milli- means "one thousandth" so to convert 4 m to millimeters you would multiply by 1000. 4 m = 4000 millimeters.
