Digital storage converter

This digital storage converter turns a numeric file or memory size from one common unit into another and returns the converted magnitude with canonical unit labels.

Supported units are bytes, kilobytes, megabytes, gigabytes, and terabytes using SI decimal powers of one thousand, plus kibibytes, mebibytes, gibibytes, and tebibytes using IEC binary powers of one thousand twenty-four. Everyday aliases such as bytes, megabyte, kibibyte, and mebibyte normalize cleanly so forms and scripts share one contract. Conversion always bridges through bytes with fixed factors, so the same input always yields the same result with no network calls, no sampling, and no date-dependent shortcuts. Typical checks include one thousand twenty-four bytes to kibibytes, one megabyte to mebibytes, and five gigabytes to gibibytes. Use it free in the browser for disk quotes, RAM labels, and homework, or call the API at $0.002 per successful request when you need reproducible storage fixtures in CI, billing pipelines, or capacity-planning tools.

How to use it

Enter your values in the form above. The tool checks them before calculating and shows the result on the same page.

Check your inputs

Use the labels and units shown next to each field. If something is missing or outside the allowed range, the page points to the field to fix.

Use it again or automate it

Use the browser tool for individual checks and the API when you need the same capability in an automated workflow.

What you can do with it

Get an answer now

Enter one set of values and see the result without building a spreadsheet or script.

Compare scenarios

Change one value at a time and rerun the calculation to understand what affects the result.

Automate repeated work

Use the API when the same calculation needs to run inside your product or workflow.

For developers — API access

Everything on this page is available programmatically. This section is for teams who want to wire it into their own systems; everyone else can just use the tool above.

API endpoint

POSThttps://api.kit.forhosting.com/conv/data-size

Prefer to automate it? One authenticated POST creates the task; the result comes back by webhook or a signed link. The same capability also runs here on the web, by email and from Telegram — and soon from our app too.

Call it from your stack

curl -X POST https://api.kit.forhosting.com/conv/data-size \
  -H "Authorization: Bearer $KIT_KEY" \
  -H "Content-Type: application/json" \
  -d '{"value":1024,"from":"B","to":"KiB"}'

const res = await fetch("https://api.kit.forhosting.com/conv/data-size", {
  method: "POST",
  headers: {
    "Authorization": `Bearer ${process.env.KIT_KEY}`,
    "Content-Type": "application/json"
  },
  body: JSON.stringify({
    "value": 1024,
    "from": "B",
    "to": "KiB"
  })
});
const { task_id } = await res.json();

import os, requests

res = requests.post(
    "https://api.kit.forhosting.com/conv/data-size",
    headers={"Authorization": f"Bearer {os.environ['KIT_KEY']}"},
    json={
    "value": 1024,
    "from": "B",
    "to": "KiB"
},
)
task_id = res.json()["task_id"]

<?php
$res = file_get_contents("https://api.kit.forhosting.com/conv/data-size", false, stream_context_create([
  "http" => [
    "method"  => "POST",
    "header"  => "Authorization: Bearer " . getenv("KIT_KEY") . "\r\nContent-Type: application/json",
    "content" => '{"value":1024,"from":"B","to":"KiB"}',
  ],
]));
$task = json_decode($res, true);

body := bytes.NewBufferString(`{"value":1024,"from":"B","to":"KiB"}`)
req, _ := http.NewRequest("POST", "https://api.kit.forhosting.com/conv/data-size", body)
req.Header.Set("Authorization", "Bearer "+os.Getenv("KIT_KEY"))
req.Header.Set("Content-Type", "application/json")
res, _ := http.DefaultClient.Do(req)

Example request

{
  "value": 1024,
  "from": "B",
  "to": "KiB"
}

Example response

{
  "task_id": "tsk_a1b2c3d4e5f6a1b2c3d4e5f6",
  "type": "conv.data_size",
  "status": "queued",
  "_links": {
    "result": "/tasks/tsk_…/result"
  }
}

The API is asynchronous: the call returns a task_id immediately and the result arrives by webhook. Polling is capped at 1 req/s per task.

Pricing

Published price — no tokens, no invented credits. A failed task is never charged.

Limits

Errors

HTTP	Code	Meaning
`401`	`unauthorized`	Missing or invalid API key.
`402`	`insufficient_balance`	Your balance doesn't cover the task price.
`404`	`unknown_type`	That task type doesn't exist.
`429`	`rate_limited`	Too many requests. Use the webhook instead of polling.
