An apostilb is a historical unit of luminance equal to 1 divided by pi candela per square metre, used mainly in older photometric and cinematography contexts.

What does millinit measure?

Millinit measures luminance at a small scale, equal to one-thousandth of a nit, useful for describing very low screen or signage brightness levels.

Why convert from apostilb to millinit?

Converting from apostilb to millinit helps update historical luminance measurements into a contemporary unit suited for very low brightness display technologies and lighting engineering.

What Is This Tool?

This converter allows users to transform luminance values measured in apostilb, a historical non-SI unit, into millinit, a modern smaller-scale unit often used for low brightness levels in screens and signage.

How to Use This Tool?

Enter the luminance value in apostilb you want to convert.
Select apostilb as the starting unit and millinit as the target unit.
Click the convert button to get the equivalent value in millinit.

Key Features

Converts luminance from apostilb (asb) to millinit (mnt) using an exact conversion rate.
Supports photometric and display technology applications related to low-brightness measurements.
Browser-based and easy to use without any installation.

Examples

2 apostilb converts to approximately 636.62 millinit.
0.5 apostilb converts to about 159.15 millinit.

Common Use Cases

Converting historical screen brightness data to modern units for display calibration.
Describing luminance for low-brightness signage and instrument panels.
Translating older photometric specifications into units suitable for current lighting engineering.

Tips & Best Practices

Ensure understanding of both units when interpreting results due to apostilb being a historical unit.
Use the tool for low luminance level conversions where millinit's smaller scale is appropriate.
Be cautious with precision and rounding when working with millinit values.

Limitations

Apostilb is a non-SI, historical unit not widely used today, which can affect practical relevance.
Millinit values represent very small luminance, requiring careful handling of precision.
Conversion depends on correct application of the relationship between the units.
