The short version: use it freely, check it carefully
Terms of use
These terms cover your use of Oil to Butter. They are deliberately brief, because this is a free reference site with nothing to sign up for.
Published January 15, 2026
Acceptance
By using this site you accept these terms. If you do not accept them, please do not use the site. We may update these terms as the site develops; the date above always reflects the current version.
What this site is for
Oil to Butter provides conversion tools and written guidance for home cooking and baking. Everything here is free to use, with no account, subscription or payment required.
Accuracy and limitations
We take accuracy seriously and test our conversion engine, but food is variable. Butter fat content differs by brand and by country, oil density shifts with temperature, and cup measurements are not standardised worldwide. Results are provided as guidance for home baking.
Nothing on this site is nutritional, dietary or medical advice. If you are managing an allergy, an intolerance, a medical condition or cooking professionally where precise nutritional declarations are required, consult a qualified professional and verify against authoritative source data.
Use of the content
You may use our conversion results freely in your own cooking, recipes and teaching. The written content, design and code of this site remain our property. Please do not republish substantial portions of our written guides without permission or a clear attributed link back to the source page.
Liability
The site is provided on an "as is" basis without warranties of any kind. To the fullest extent permitted by law, we are not liable for any loss or damage arising from your use of the site or reliance on its results — including, plainly, a bake that does not turn out as you hoped.
Nothing in these terms limits liability that cannot lawfully be limited, including liability for death or personal injury caused by negligence, or for fraud.
External links
We sometimes link to other sites. We do not control them and are not responsible for their content, accuracy or privacy practices.
Availability
We aim to keep the site available, but we do not guarantee uninterrupted access. We may change, suspend or withdraw any part of the site at any time.
Governing terms
These terms are governed by the laws of England and Wales. If any provision is found unenforceable, the remaining provisions continue in full effect.
