Common Mistakes

⚠️

Mistake: Confusing μ (mu) with µ (micro sign)

Fix: The micro sign µ is technically a different character (U+00B5) from Greek mu μ (U+03BC), though they look identical. Use μ for Greek text and µ for measurements.

⚠️

Mistake: Using u instead of μ in scientific notation

Fix: Use μ (mu) for micro- prefix in measurements like μm (micrometer). Writing "um" instead of "μm" is incorrect in scientific contexts.
