Using RocketCalc
RocketCalc (rocketcalc.io) is run by Kevin Flahaut (“we”, “us”). By using the site you agree to these terms and to the Privacy Policy. If you don’t agree, please don’t use the site.
What RocketCalc is
RocketCalc is a free set of unit converters and calculators. Every result shows the formula and the math behind it. There are no ads, and every converter works without an account.
We may add, change or remove converters and features at any time, and the site may occasionally be unavailable for maintenance or reasons outside our control.
Check before you rely on a result
We work hard to make every result correct: conversions use exact, published factors and are checked by automated tests. Even so, mistakes can happen, and results are rounded to the precision you choose.
Results are for general information only. Don’t rely on RocketCalc alone where a mistake could cause harm or loss, for example medication doses, medical, engineering, structural, aviation, legal or financial work. Always confirm those numbers with a qualified professional or an authoritative source.
Optional accounts
Accounts are optional and let you keep favorites and history across devices. If you create one:
- Give an email address you control, and keep access to it secure (we sign you in with a one-time link, so there’s no password to share).
- You’re responsible for what happens under your account.
- You can delete your account at any time, which deletes the data linked to it.
- We may suspend or remove accounts that break these terms.
Fair use
Please use RocketCalc the way you’d use any public website. Don’t:
- scrape, copy or mirror the site or its data in bulk, or send automated traffic heavy enough to slow it down for others;
- try to break, probe or get around the site’s security, or reach areas that aren’t public;
- use the site for anything unlawful, or to submit content meant to mislead or harm others;
- present RocketCalc’s pages as your own, or suggest we endorse you when we don’t.
Linking to any RocketCalc page, including a specific result, is always welcome.
Content and your results
The site’s design, text, explanations and code belong to Kevin Flahaut. The numbers you convert and the results you get are yours: copy, share and use them however you like.
Other services
RocketCalc relies on a few outside services, such as our web host, Supabase for accounts and, if you allow it, Google Analytics. Their own terms and privacy policies apply to how they run. Links to other websites are provided for convenience; we aren’t responsible for their content.
No warranties
RocketCalc is provided “as is” and “as available”, free of charge. To the fullest extent the law allows, we make no warranties of any kind, express or implied, including that the site will be accurate, complete, uninterrupted, error-free or fit for a particular purpose.
Limits on liability
To the fullest extent the law allows, Kevin Flahaut won’t be liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of data, profits or business, that comes from using (or not being able to use) RocketCalc or relying on its results, even if we were told such damage was possible.
Because the site is free, our total liability for any claim relating to it is limited to US $50. Some places don’t allow these limits, so they may not all apply to you.
Changes
We may update these terms as the site grows (for example when accounts launch). When we do, we’ll change the “Last updated” date at the top of this page. Using the site after an update means you accept the new terms.
Governing law
These terms are governed by the laws of the Commonwealth of Virginia, United States, without regard to its conflict-of-law rules. Any dispute will be handled in the state or federal courts located in Virginia, unless the law where you live gives you the right to bring it elsewhere.
If any part of these terms can’t be enforced, the rest still applies.
