Convertitore Unità di Misura
Domande Frequenti
Tutto quello che devi sapere sul convertitore di unità
Le conversioni sono precise?
Sì, tutte le conversioni utilizzano i fattori di conversione standard riconosciuti a livello internazionale (SI). Per la temperatura vengono usate le formule esatte di conversione tra Celsius, Fahrenheit e Kelvin. Per il tempo, i mesi sono calcolati come 30 giorni e gli anni come 365 giorni.
Quali sistemi di misura sono supportati?
Il convertitore supporta sia il Sistema Internazionale (SI) sia il sistema imperiale anglosassone. Include unità metriche (mm, cm, m, km, g, kg, litri) e unità imperiali (pollici, piedi, iarde, miglia, once, libbre, galloni). Per i volumi si usano le misure americane (US).
Come funziona la conversione della temperatura?
La temperatura è l'unica grandezza che non usa una conversione lineare semplice. Le formule usate sono: da Celsius a Fahrenheit: F = C × 9/5 + 32; da Celsius a Kelvin: K = C + 273,15; da Fahrenheit a Celsius: C = (F - 32) × 5/9.
I calcoli avvengono nel mio browser?
Sì, tutte le conversioni vengono eseguite in tempo reale direttamente nel browser, senza inviare dati a server esterni. Lo strumento funziona anche offline una volta caricata la pagina.
Are the conversions accurate?
Yes, all conversions use internationally recognised standard conversion factors (SI). For temperature, the exact conversion formulas between Celsius, Fahrenheit and Kelvin are used. For time, months are calculated as 30 days and years as 365 days.
Which measurement systems are supported?
The converter supports both the International System (SI) and the Imperial system. It includes metric units (mm, cm, m, km, g, kg, litres) and imperial units (inches, feet, yards, miles, ounces, pounds, gallons). For volumes, US measures are used.
How does temperature conversion work?
Temperature is the only quantity that does not use a simple linear conversion. The formulas used are: Celsius to Fahrenheit: F = C × 9/5 + 32; Celsius to Kelvin: K = C + 273.15; Fahrenheit to Celsius: C = (F - 32) × 5/9.
Do calculations happen in my browser?
Yes, all conversions are performed in real time directly in the browser, without sending data to external servers. The tool also works offline once the page is loaded.
Does my data stay private?
Yes, and not because we promise it: this tool runs entirely inside your browser. What you type or upload never leaves your device, so it never reaches a server of ours and there is nothing we could keep, read or lose. You can check it yourself: open the page, disconnect from the internet, and the tool keeps working.
Do you store what I enter?
No. There is no database behind this tool: we do not store your files, your text or your results. When you close the tab nothing is left — not here with us, because it never arrived, and not anywhere else.
Do you profile me? Are you GDPR compliant?
We do not profile you: there is no account to create, we never ask for your email to use a tool, and we keep no profile of what you do. We are an Italian company and we work under the GDPR and the other European rules, with the privacy notice and the consent request in plain sight. One thing we say in full rather than hiding it behind a slogan: the ads on the page are Google's, and Google may use cookies to personalise them. You decide from the consent banner: if you say no the ads stay, but they are not personalised, and the tool works exactly the same.
If it is free, how do you make money?
From the ads on the page, and that is all. We do not sell your data, there is no hidden paid plan, there is no limit that eventually asks for your card, and you do not have to sign up. The ads pay for the servers and for the time we spend writing the tools: that is how we can keep them open to everyone.
