Worked example: starting scenario
| Speed in kilometers per hour | 100 |
|---|
| Speed in miles per hour | 62.1371192237 mph |
|---|---|
| Speed in meters per second | 27.7777777778 m/s |
| Speed in knots | 53.9956803456 kn |
| Speed in feet per second | 91.1344415281 ft/s |
| Minutes per kilometer pace | 0.6 min/km |
Important limitations
Pace is undefined at zero or negative speed.
Speed and pace are reciprocals
At 10 km/h the pace is 6 minutes per kilometer, while at 20 km/h it is 3 minutes per kilometer. A value of 0.6 min/km is 36 seconds per kilometer, not 60 seconds. The converter uses one international mile = 1.609344 km and one knot = 1.852 km/h. A nonpositive speed has no positive travel pace in this form.
