Convert km/h to m/s instantly: just divide by 3.6. Physics homework, wind warnings and treadmill specs, with the exact math and a copy button.
Divide by 3.6 — or multiply by 0.28, if your calculator believes in round numbers.

pro tips
Anchor: divide by 3.6. 36 km/h is 10 m/s — the one pair worth memorizing.
City speeds: 50 km/h is about 14 m/s, which is why braking distances look so brutal in physics textbooks.
The multiply-by-0.28 shortcut works, but dividing by 3.6 survives no-calculator exams.
what it does
The kilometers-per-hour-to-meters-per-second trick divides by 3.6. It turns the road speed into the physicist's speed: 36 km/h becomes exactly 10 m/s, and suddenly the answer fits inside an equation.
It shows up whenever numbers go back to class: a 90 km/h speed limit that a physics problem demands in m/s (25, if you're wondering), wind gusts the news gives in km/h but the sailing app wants in m/s, and treadmill spec sheets that can't commit to one system and honestly shouldn't have to.
The rough version: divide by 4 and add 10%. Seventy-two km/h becomes 18 plus a nudge — 20 m/s. Or just remember 3.6 goes both ways: multiply one way, divide the other, and the homework finishes itself.
Type any km/h number and the widget answers in m/s instantly, math in the hint. Click the result to copy it, and hit swap when the question turns back into a road speed — the m/s-to-km/h version multiplies its way home.
quick answers
How do you convert km/h to m/s?
Divide by 3.6. Highway 108 km/h becomes 30 m/s, and the equation accepts it.
What is 100 km/h in m/s?
27.78 m/s — highway speed wearing physics clothes.
Why divide by 3.6?
Same arithmetic, reversed: 1,000 meters per kilometer and 3,600 seconds per hour, so the hour shrinks the number.
Which number is bigger, m/s or km/h?
km/h runs 3.6 times bigger for the same speed. A car at 14 m/s is doing 50 km/h — same motion, different audience.
