Why this conversion matters in chemistry
A cuvette path is 1 cm. A spectrometer slit is a few mm. The bench is built around centimeters, the way humans measure things by eye. Most chemistry equations, when written cleanly in SI, want meters. Dividing by 100 is the bookkeeping step that takes a 1 cm cuvette path to 0.01 m so it can sit next to a wavelength in nm and a molar absorptivity in m² mol⁻¹ without the units fighting. The SI conversion of molar absorptivity is the one that exposes the issue most often — a published ε of 15,000 M⁻¹ cm⁻¹ becomes 1,500 m² mol⁻¹ once everything is in base SI (the factor is 0.1 m² mol⁻¹ per M⁻¹ cm⁻¹), and getting there cleanly takes the conversion from centimeters to meters as the first step.

Worked Examples
The defining identity — 100 cm is exactly 1 meter, no rounding involved.
A standard UV-Vis cuvette path length, expressed in SI for an equation that wants meters throughout.
About the path length of a typical IR gas cell, useful for vibrational absorbance work where a longer path increases sensitivity.
A 1 mm short-path cuvette, used when concentration is high enough that a 1 cm cell would saturate the detector.
