Enter a value in inches and this converter returns centimeters along with the reverse direction, so you can sanity-check either way without re-typing.

    },
    {
      "q": "What do I need to enter?",
      "a": "Just one value: value in inches. Each field starts with a sensible default, so you can change one number at a time and watch the result move."
    },
    {
      "q": "What does the centimeters (cm) result mean?",
      "a": "It is returned as a decimal number and updates live as you edit the inputs, so you can compare two or three versions of a scenario in a few seconds."
    },
    {
      "q": "Is this calculator free, and do I need an account?",
      "a": "Yes, it's free, and no account is required. Nothing you type is stored on our servers — the maths runs entirely in your browser."
    },
    {
      "q": "How accurate is the result?",
      "a": "It applies the standard formula exactly, so the arithmetic is precise. Estimates assume standard, average conditions — local rules, pricing, and materials vary."
    },
    {
      "q": "Who is this tool for?",
      "a": "It's built for anyone doing everyday planning maths — a quick estimate that would otherwise need four browser tabs and a calculator app."
