Speed Converter

Speed Converter Online Tool Description

Ever tried to compare a plane’s speed in knots with a car’s speed in kilometers per hour? Or wanted to know how fast something moves in furlongs per fortnight just for fun?

Why We Created This Tool

Let’s face it — speed units can get weird fast.

Some are metric, some are imperial, and then there are the oddly specific ones like knots or light speed. And of course, someone had to throw in furlongs per fortnight just to keep things interesting.

We built this tool to handle every one of them — from the serious to the silly. Whether you’re solving a physics problem, planning travel, or just curious about obscure measurements, we’ve got you covered.

Who Should Use This Tool

This tool is perfect for:

• Students learning about motion and units of measurement

• Travelers and navigators converting between knots, km/h, or mph

• Engineers and scientists working with precise speed data

• Curious minds who just want to know how fast a cheetah runs in furlongs per fortnight

• Gamers and coders working with unit systems in simulations

No matter who you are, if you’re working with speed — this tool makes the math easy.

How to Use This Tool

1. Choose your original unit (e.g., km/h, m/s, knots)

2. Enter the speed value

3. Pick the unit you want to convert to

4. Hit the “Calculate” button

5. Get your result instantly — and yes, you can switch to speed of light if you want to feel fast.

Example:

Convert 120 km/h to mph → You get 74.5646 mph
