ツールの紹介

Convert between everyday units — length, weight, temperature, volume, area, speed, time, and data — with a recent-conversion history that stays on this page.

ツール概要

Most unit converters bury their logic behind network calls. This one uses a small table of base-unit factors, so every conversion is a plain multiplication done instantly in your browser. Temperature uses an affine transform rather than a factor, because 0 °C is not 0 °F. Pick a category, type a value, choose your units, and the result appears immediately.

ユースケース

  • Use Unit Converter when you need fast convert units across length, mass, temperature, speed, area, and volume with category switching and recent history.
  • Handle math workflows directly in the browser with no install required.
  • Support SEO long-tail intent by covering quick checks, troubleshooting, and one-off conversions.

よくある質問

Is the KB / KiB distinction respected?+
Yes. KB, MB, GB, TB use powers of 1000 (the SI prefix). KiB, MiB, GiB, TiB use powers of 1024 (the binary prefix).
Where is currency conversion?+
Currency rates change constantly and require a live data source. This tool only does conversions that are defined by fixed factors or formulas.
Is the history saved after I leave the page?+
No. The history is in-memory only and resets on reload — keeping the tool private and stateless.
