Luminous Flux converter

hectolumen to nanolumen

Convert hectolumen (hlm) to nanolumen (nlm). Use an editable luminous flux converter, conversion formula, and reference table.

100,000,000,000

1 hlm = 100,000,000,000 nlm

Calculated in your browser

Conversion formula

nlm = hlm × 100,000,000,000

One hectolumen equals 100,000,000,000 nanolumen. Multiply your value in hectolumen by this factor to get nanolumen. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 hectolumen:
5 × 100,000,000,000 = 500,000,000,000 nlm

About these measurements

Luminous flux measures the visible-light output weighted by human visual sensitivity.

The base reference used here is the lumen. One hectolumen is 100 base units; one nanolumen is 1e-9 base units.

Important distinctions

Lumens measure light output; lux measures illumination per unit area.

Precision

The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.

Common questions

How do I convert hlm to nlm?
