Frequently Asked Questions
How do I convert between speed units?
km/h to m/s: divide by 3.6. m/s to km/h: multiply by 3.6. mph to km/h: multiply by 1.609. Knots to km/h: multiply by 1.852.
How do I calculate travel time from distance and speed?
Time equals distance divided by speed. For example, 200 km at 80 km/h takes 2.5 hours. Remember to account for breaks, traffic, and speed limits.
What is the Speed Calculator?
The speed calculator computes speed, distance or time from two known values and converts between units.
How does the Speed Calculator work?
Enter two of the three values: distance, time or speed. The calculator determines the third: v = s/t, s = v*t, t = s/v. Conversion between km/h, m/s, mph and knots is built in.
Key Data and Facts
v = s / t. 1 km/h = 0.2778 m/s. 1 mph = 1.609 km/h. 1 knot = 1.852 km/h. Speed of light: 299,792,458 m/s.
Step-by-Step Guide
How to calculate Geschwindigkeit, Strecke oder Zeit step by step: 1. Zwei bekannte Groessen enter: Strecke (s), Zeit (t) oder Geschwindigkeit (v). 2. Formeln: Geschwindigkeit = Strecke / Zeit (v = s / t). Strecke = Geschwindigkeit x Zeit (s = v x t). Zeit = Strecke / Geschwindigkeit (t = s / v). 3. Einheiten beachten: km/h und hours ergeben km. m/s und Sekunden ergeben Meter. Umrechnung: km/h in m/s: dividieren durch 3,6. m/s in km/h: multiplizieren mit 3,6. 4. Durchschnittsgeschwindigkeit calculate: v = Gesamtstrecke / Gesamtzeit. Achtung: Der average zweier Geschwindigkeiten ist nicht das arithmetische Mittel, sondern das harmonische Mittel. 5. Weitere Einheiten: 1 mph = 1,609 km/h. 1 Knoten = 1,852 km/h. Schallgeschwindigkeit (Luft 20 Grad): 343 m/s = 1.235 km/h.
Calculation Example
Auto faehrt 210 km in 2,5 hours: v = 210 / 2,5 = 84 km/h. Bei 120 km/h fuer 350 km: t = 350 / 120 = 2,92 h = 2 h 55 min.
