What is Science Tools?
Science tools are browser-based calculators for chemistry and physics — molar mass, the periodic table, kinematics, significant figures and scientific-notation conversion. They run client-side, free and instantly, so students and researchers can compute without installing anything.
What are science tools?
These calculators handle the recurring computations of school and lab science: working out a molar mass, looking up an element, solving a kinematics problem, or rounding to the correct number of significant figures. Each gives an instant, shareable result.
They run entirely in your browser — free, private and offline-capable once loaded.
Why client-side?
- Privacy: sensitive data (API keys, payloads, passwords) never leaves your device.
- Speed: no network round-trip — results appear as you type.
- Reliability: works offline once loaded.
- Cost: always free, no signup or rate limits.

Frequently asked questions
Are these science tools accurate enough for coursework?
Yes. They use standard constants and formulae (atomic weights, SI units) suitable for school and undergraduate work. For published research, always verify against primary references.
Do they handle significant figures correctly?
The significant-figures calculator follows standard rounding rules, and other tools let you control precision so your answers respect the right number of significant figures.
