🔒

Local Device Privacy

Every operation runs in your browser with plain JavaScript. Values never leave your device.

How to Use the Speed Converter

  1. Enter the Amount you want to convert. Commas are ignored so 1,250.5 works.
  2. Choose the From unit and the To unit from the dropdowns.
  3. Read the large result card: the converted value, the plain sentence, and the exact factor used.
  4. Check the All Units grid below to see your input in every other speed unit instantly.
  5. Use Swap to reverse direction, Copy Result to copy, or Download Report to save a text file with all conversions.

Understanding Speed Units

Speed measures distance per time. One meter per second equals 3.6 km/h, one mph equals 1.609 km/h, and one knot equals 1.852 km/h. Converting multiplies by the ratio of factors through m/s.

When to use which unit

Use m/s for science, km/h for cars worldwide, mph for cars in US/UK, and knots for ships and aircraft. For example 100 km/h is 62.13 mph and 53.99 knots.

Honest limitations

Display rounding hides trailing noise. Values beyond 1e12 m/s switch to exponential form. The tool does not handle Mach or ft/s - for those, use Length Converter patterns.

Privacy and Client-Side Security

Privacy Guarantee: All conversions occur locally inside your browser. Your numbers and selected units are never transmitted, stored, or recorded on remote servers.

Many online converters send your inputs to a server. TinyToolzz keeps everything in-page with plain JavaScript.

Because nothing is uploaded, there is no waiting, no account, and no copy retained anywhere. Your values exist only in the tab's memory and are discarded when you close the page or click Clear.

Frequently Asked Questions

How do I convert km/h to mph?
Enter the value, choose Kilometer per hour (km/h) as From and Mile per hour (mph) as To. The tool multiplies by 0.621371 because 1 km/h equals 0.621371 mph.
How many knots is 1 m/s?
One meter per second equals 1.94384 knots. One knot equals 1.852 km/h or 1.15078 mph.
What precision does the converter display?
Results are shown up to 9 decimal places with trailing zeros trimmed. Very large or very small values switch to exponential notation.
Is my conversion sent to a server?
No. All math runs locally in your browser with JavaScript. Nothing is transmitted or logged.
Can I convert in both directions?
Yes. Choose any unit as From and any as To. Use the swap button to reverse instantly. The All Units matrix shows every other unit at once.
