How to use it

  1. 01

    Choose or write a quantity

    Use a category converter or enter a compound expression with units, multiplication, division and integer powers.

  2. 02

    Verify dimensions

    The local parser converts through base SI factors and rejects incompatible target dimensions.

  3. 03

    Reuse the evidence

    Inspect factors and steps, batch-convert rows and export a Markdown or CSV artifact.

Frequently asked questions

Can it calculate compound engineering formulas?

Yes. Expressions can combine numeric factors, units, parentheses, multiplication, division and integer powers before a target arrow.

How are temperatures handled?

Celsius, Fahrenheit and Kelvin use affine conversion for standalone quantities; mixing offset temperatures into compound formulas is deliberately rejected.

Are all conversions legally exact?

No. The reference marks defined factors where applicable, while formatted output and measured inputs still carry practical uncertainty.

Is any data uploaded?

No. Formula parsing, conversion, batching and report generation run in the browser.
