feet per second → meters per second

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

1 feet per second = 0.3048 meters per second. To convert, multiply the number of feet per second by 0.3048. The reverse direction is meters per second → feet per second.

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

Paid call (JavaScript agent)

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-feet-per-second-to-meters-per-second")).json();
let n = 0;
while (lz(createHash("sha256").update(c.challenge + ":" + n).digest()) < c.difficulty) n++;
await fetch("https://agent402.tools/api/convert/feet-per-second-to-meters-per-second", { method: "GET", headers: { "X-Pow-Solution": c.token + ":" + n } });
