Hi Product Hunt! Scientific Converters was built to get unit conversions exactly right and to show where each number comes from.
It started with the units that come up in labs, HVAC, filtration and materials testing, like sccm to SLPM and inches of water to pascals. Every factor lists its source: mostly NIST and the BIPM, plus standards like ASTM and ISO for textile and other niche units. 388 of the 396 are exact; the page says so when one is not.
What's there today:
- 396 units across 50 categories
- 400+ calculators for engineering, physics, chemistry, SAT, ACT and GATE
- A bulk converter: paste a column from Excel, convert it all at once
- A free JSON data file, no key and no rate limit (CC BY 4.0)
There's no paywall and no sign-up. If a number looks wrong or a unit from your field is missing, please leave a comment here.
