meters per second → kilometers per hour

Convert meters per second to kilometers per hour (speed). Pass ?value=N.

1 meters per second = 3.6 kilometers per hour. To convert, multiply the number of meters per second by 3.6. The reverse direction is kilometers per hour → meters per second.

Common meters per second to kilometers per hour values

meters per second	kilometers per hour
1 meters per second	3.6 kilometers per hour
2 meters per second	7.2 kilometers per hour
5 meters per second	18 kilometers per hour
10 meters per second	36 kilometers per hour
25 meters per second	90 kilometers per hour
100 meters per second	360 kilometers per hour
1000 meters per second	3600 kilometers per hour

The response is HTTP 402 Payment Required with exact payment requirements. Any x402 v2 client pays automatically and retries:

No wallet? Pay with compute

This is a pure-CPU tool, so an agent without a wallet can pay with proof-of-work instead of USDC: fetch a challenge, solve it (16 leading zero bits), and resend with the X-Pow-Solution header.

import { createHash } from "node:crypto";
const lz = (b) => { let t = 0; for (const x of b) { if (!x) { t += 8; continue; } t += Math.clz32(x) - 24; break; } return t; };
const c = await (await fetch("https://agent402.tools/api/pow/challenge?slug=convert-meters-per-second-to-kilometers-per-hour")).json();
let n = 0;
while (lz(createHash("sha256").update(c.challenge + ":" + n).digest()) < c.difficulty) n++;
await fetch("https://agent402.tools/api/convert/meters-per-second-to-kilometers-per-hour", { method: "GET", headers: { "X-Pow-Solution": c.token + ":" + n } });
