Metre per second facts for kids

A metre per second is a way to measure how fast something is moving. It tells you the distance an object travels in metres during one second of time. It's a standard unit of measurement used around the world, part of the SI system.

You'll often see it written as m/s or m·s^-1. For very fast things, like objects in astronomy, people sometimes use kilometres per second, which is 1000 metres per second.

How to Change Units

Sometimes you need to change metres per second into other units, like miles per hour or kilometres per hour. Here are some common ways to convert:

• 1 metre per second is about 3.2808 feet per second.
• 1 metre per second is about 2.2369 miles per hour.
• 1 metre per second is exactly 3.6 kilometres per hour (km/h).

And here are some conversions the other way around:

• 1 foot per second is exactly 0.3048 metres per second.
• 1 mile per hour is about 0.4470 metres per second.
• 1 kilometre per hour is about 0.2778 metres per second.

If you're talking about really fast speeds, like a meteor entering Earth's atmosphere:

• 1 kilometre per second is about 0.6213 miles per second.
• 1 kilometre per second is about 2,237 miles per hour.
