Why PlainConvert?
Most converter sites are either link-farms with hundreds of half-baked tools, or aggressive marketing pages with cookie banners and pop-ups. PlainConvert keeps the surface small on purpose: one clear converter per page, an explanation that earns its space, and a quick-reference table for the values people actually look up.
