Accuracy & Reliability
Our tools use standard conversion formulas and calculation methods. While we strive for high accuracy, we recommend double-checking important calculations and using professional tools for critical applications like medical, engineering, or financial decisions.
We use internationally recognized standards: SI units for metric measurements, Imperial units for US customary measurements, and official conversion factors from NIST (National Institute of Standards and Technology) and other authoritative sources.
We typically show results with reasonable precision (usually 2-6 decimal places depending on the tool). Some tools allow you to adjust the precision. For highly precise calculations, we recommend using specialized scientific calculators.
