Formula

Formula
% = frac × 100

Multiply any value in fractions (dimensionless ratio) by 100 to obtain the value in percent (10⁻²).

Worked example

FAQ

What is the conversion factor from frac to %?
1 frac equals 100 %. To convert, multiply the value in fractions (dimensionless ratio) by 100.
How do I convert 1 frac to %?
1 frac = 100 %. For any value, multiply by 100.
How do I convert % back to frac?
Divide by the same factor — or equivalently, multiply by 0.01. So 1 % = 0.01 frac.
When would I need to convert fraction (dimensionless ratio) to percent (10⁻²)?
Concentration-ratio conversions between frac and % are used in trace-analysis, gas-composition work, environmental reporting and process-chemistry datasheets. These conversions are dimensionless: they do NOT cover mg/L, g/L, mol/L, normality, equivalents, mass-percent, volume-percent, ppmw or ppmv — those require solution density and/or molecular weight. Note: ppt here means parts per trillion (10⁻¹²), not parts per thousand.
Is the conversion exact?
Yes. Both frac and % are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
