Nit (nt)

Definition: An alternative name for candela per square meter, numerically and dimensionally identical to the SI unit — "nit" is simply the everyday, shorter name used in the display and consumer electronics industry.

History: The name derives from the Latin "nitere" ("to shine") and came into common use in the mid-20th century as a convenient shorthand once candela-per-square-meter became the standard luminance unit for engineers working with screens and displays.

Current use: The universal unit quoted in TV, monitor, smartphone, and projector brightness specifications — a typical smartphone screen might reach 500-1,000+ nits, and HDR displays are often rated at 1,000 nits or higher.

Millilambert (mL)

Definition: One-thousandth of a lambert, offering a more practically sized CGS luminance unit for typical indoor and screen-brightness magnitudes than the full lambert.

History: Introduced as the lambert proved too large a unit for everyday luminance readings — most real-world surfaces and early cathode-ray displays measured in the millilambert range rather than whole lamberts.

Current use: Historically used in early display and photometric engineering, including some vintage radar and oscilloscope screen brightness specifications, before nits and foot-lamberts became standard.

About These Parameters

Value
The luminance value you want to convert, expressed in the "From" unit. Accepts decimals, so you can enter anything from a faint scotopic reading in skots to a display's rated brightness in nits.
From Unit
The unit your input value is currently measured in — a monitor spec sheet's nits, a cinema calibration report's foot-lamberts, or a scientific instrument's candela per square meter.
To Unit
The unit you want the result converted into. Use the swap button to flip From and To instantly and compare figures across display, cinema, and scientific contexts.

How Luminance Conversion Works

The Formula

Every unit here is defined by a fixed multiplier relative to candela per square meter. To convert a value from one unit to another:

result = value × (factor of "From" unit ÷ factor of "To" unit)

For Nit → Millilambert: multiply by 0.31415927. For example, 1 nt × 0.31415927 = 0.31415927 mL.

Nits vs. Candela per Square Meter

A nit and a candela per square meter are exactly the same physical quantity — "nit" is simply the shorter, everyday name adopted by the display and consumer electronics industry. When a phone, TV, or monitor spec sheet quotes "1,000 nits," that number is identical to 1,000 cd/m² in a scientific paper. The two names exist for context, not physics: engineers and physicists tend to write cd/m², while marketing copy, review sites, and display datasheets almost universally write nits.

CGS vs. SI Luminance Units

Several units on this page — the stilb, lambert, apostilb, blondel, bril, and skot — predate the modern SI system and come from the centimeter-gram-second (CGS) system of photometric units used in early 20th-century physics. They were built around the idea of a perfectly diffusing ("Lambertian") surface rather than the candela directly, which is why their conversion factors to cd/m² involve π-related constants (a lambert, for instance, equals 1/π candela per square centimeter). Most of these CGS units have been superseded by candela-per-square-meter and its nit alias in modern engineering, but they still surface in legacy scientific literature, older photometric instruments, and specialized fields like vision research that never fully migrated to SI.

Example

A luminance of 1 nt equals 0.31415927 mL. For scale, a typical smartphone screen runs around 500-1,000 nits, a calibrated cinema screen is set to roughly 14-16 foot-lamberts, an overcast sky reads around 2,000-4,000 cd/m², and the full moon's surface luminance is only about 2,500 cd/m² despite looking far brighter against a dark night sky.

Frequently Asked Questions

How many Millilamberts are in 1 Nit?

1 Nit (nt) equals exactly 0.31415927 Millilamberts (mL).

What's the difference between luminance and brightness?

Luminance is the objective, physically measured quantity — candela per square meter, or nits — while "brightness" is often used loosely to describe the subjective perception of how light a surface looks, which also depends on surrounding contrast and the viewer's eye adaptation. Luminance is what a light meter measures; brightness is what a person reports seeing.

Is a nit the same as a candela per square meter?

Yes — a nit and a candela per square meter (cd/m²) are exactly the same unit under two different names. "Nit" is the informal name used throughout the display and consumer electronics industry, while cd/m² is the formal SI name used in scientific and engineering contexts.

Why do cinema screens use foot-lamberts instead of nits?

The film and projection industry standardized on foot-lamberts decades before nits became common in consumer electronics, and SMPTE calibration standards for theatrical and home-theater screens (typically 14-16 foot-lamberts) are still written in that unit today. Converting to nits (1 fL ≈ 3.43 cd/m²) shows that cinema screens are actually much dimmer than a modern smartphone or TV display, which is intentional for a dark viewing room.

Why are there so many old CGS luminance units like the stilb and apostilb?

Before the SI system standardized photometry around the candela and candela-per-square-meter in the mid-20th century, different countries and scientific traditions developed their own luminance units within the centimeter-gram-second (CGS) system — the stilb and lambert in general use, the apostilb and its French-system twin the blondel for illuminated surfaces, and the extremely small bril and skot for vision research into low-light perception. Most have fallen out of everyday use but still appear in older instruments, legacy literature, and specialized scientific fields.

How accurate are these conversions?

Every conversion factor used here is the exact, internationally recognized relationship between the underlying luminance units — results are limited only by floating-point display precision, not by rounded conversion constants.
