What is a unit converter?

A unit converter turns a measurement in one unit into the equivalent in another — kilometres to miles, kilograms to pounds, Celsius to Fahrenheit, gigabytes to megabytes. It's one of the most-searched utilities on the web because the need is universal and constant: a cook halving a metric recipe, an engineer reconciling imperial and SI drawings, a traveller reading a foreign speed-limit sign, a developer sizing a data export. The canonical tools — the Google search-box converter, rapidtables, unitconverters.net, convertworld — all do the same core job: pick a category, pick two units, type a number, read the answer instantly. The platonic converter is fast, exact, and never makes you think about which direction you meant; the temperature edge case (offsets, not ratios) is the one place naive implementations get it wrong, turning 0°C into 0°F instead of 32.

Common features

  • Categories for length, weight/mass, temperature, volume, area, speed, time, and digital storage
  • Instant, as-you-type two-way conversion
  • A swap button to reverse the from/to direction
  • Correct offset-based temperature maths (C / F / K), not just ratios
  • Common-pair shortcuts (km↔miles, kg↔lbs, cm↔inches)
  • Exact round-tripping so A→B→A returns the original value
  • Decimal and binary data-storage units (KB/MB/GB vs KiB/MiB/GiB)
  • Sensible rounding with enough significant figures to stay precise
  • Last category and unit selection remembered on the device
  • A precision-instrument visual that reads like a bench tool

Real-world examples

Halving a metric recipe

A home cook converts 500 grams to ounces and 180°C to Fahrenheit in seconds, on their own ad-free page, without a recipe site hijacking the search result.

Reconciling drawings on a job site

An engineer flips between millimetres and inches all afternoon, using the swap button and the remembered units so each conversion is two taps instead of a fresh setup.

Sizing a data export

A developer checks how many gigabytes a 4,500,000,000-byte dump is in both decimal and binary units, settling a 'GB vs GiB' disagreement with the exact numbers.

Why FloopFloop fits unit converter projects

A unit converter is the kind of tool that should be instant, exact, and free of the ad-stuffed pages the search results are full of. FloopFloop ships the converter you want — the categories you use, the units you care about, the precision your work needs — on your own domain, running entirely in the browser. The machinist's-bench look that ships by default reads like a real instrument rather than a content farm, and the whole thing is one prompt away from being whatever suits you.

Build a unit converter with categories for length, weight/mass, temperature, volume, area, speed, time, and digital storage. Pick a category, choose 'from' and 'to' units, type a value, and see the result update instantly with a swap button to reverse the direction. Handle the offset-based temperature conversions (Celsius/Fahrenheit/Kelvin) correctly, not just ratios. Visual: a precision-instrument bench — a brushed-metal face plate, recessed unit selectors, and a glowing readout like a machinist's calliper.

Create a measurement converter like rapidtables or unitconverters.net. Factor-based conversion for length, mass, volume, area, and speed run entirely in the browser with no network calls. Common pairs front and centre: km to miles, kg to lbs, cm to inches, Celsius to Fahrenheit.

Build a metric-to-imperial converter for everyday use. Big input, a category switcher, and a live result, plus a short list of common conversions (miles to km, lbs to kg, inches to cm) as one-tap shortcuts. Remember the last category and units on the device.

Build a developer-friendly converter that includes a data-storage category (bytes / KB / MB / GB / TB, both decimal and binary) alongside the everyday length / weight / temperature ones. Keep the arithmetic exact enough that round-tripping a value returns the same number.

よくある質問

How is this different from the Google unit converter or rapidtables?
Those work, but they're someone else's page wrapped in ads and tracking, and you can't change the categories or the look. The version FloopFloop generates is yours: it runs every conversion in the browser, has no telemetry, and you can add the units you actually use (nautical miles, troy ounces, your own custom factor) without asking for an API quota.
Does it handle temperature correctly?
Yes. Temperature isn't a simple ratio — Celsius, Fahrenheit, and Kelvin need offset-based formulas — and the template handles those properly, so 0°C converts to 32°F rather than 0. The other categories (length, mass, volume, area, speed, storage) are factor-based and exact.
Is it accurate enough to rely on?
The conversions use standard published factors and run in double precision, so round-tripping a value (convert A→B then B→A) returns the original number. For most everyday and engineering uses it's as accurate as the factors themselves; ask the AI to add more decimal places or a specific high-precision factor if you need it.
Can I add my own units or categories?
Yes. The unit factors are a plain data file — ask the AI to add a cooking category (cups / tablespoons / millilitres), currency-style custom factors, or a fuel-economy converter, and it ships in the next refinement.
Does it work offline?
Once the page has loaded, yes — there are no network calls for the conversions themselves. The only server surface is the /api/health probe, so the converter keeps working even on a flaky connection.
