Dimensional Analysis Engine

Enter any mathematical expression with units. MetaNumber determines the dimensional signature automatically.

How to use: Use singular units (mile, foot, second). Expressions auto-convert to SI / metric.
To convert to specific units, use the ! operator: 60 * mile / hour ! meter/second
The "Convert to" box does the same as !.

About MetaNumber

The probe-value algorithm evaluates any expression 24 times, perturbing each of 23 base unit dimensions, and extracts the dimensional signature from the logarithmic response. No symbolic algebra, no type annotations. 199 tests, zero dependencies. Patent pending.
