millicandela to microcandela formula
Milli is 10^-3 and micro is 10^-6. They are three powers of ten apart, so every mcd to µcd conversion uses the exact factor 1,000.
µcd = mcd × 1,000
200 mcd × 1,000 = 200,000 µcdmcd to µcd table

Understanding millicandelas and microcandelas
A millicandela (mcd) is 10⁻³ of the base unit (candela) and a microcandela (µcd) is 10⁻⁶. They sit three powers of ten apart, so going from mcd to µcd means multiplying by exactly 1,000 — move the decimal point three places to the right.
Millicandelas are how indicator LEDs are binned — a dim panel lamp is a few mcd, a bright indicator several thousand. Because candela is intensity rather than total output, the mcd figure is inseparable from the viewing-angle spec printed beside it.
This calculator shifts the decimal exponent rather than multiplying in binary floating point, so 200 mcd returns exactly 200,000 µcd — not a value with a trailing rounding error.
Common mcd to µcd mistake
Candela is intensity per steradian, lumen is total flux. A narrow 15° LED at 5000 mcd emits far fewer lumens than a 120° LED at the same mcd rating, so comparing mcd values across beam angles is meaningless.
When to use mcd vs µcd
millicandelas and microcandelas are used for LED brightness, indicator lights, displays, and low-light sensor calibration. Use the larger milli unit when the number becomes easier to scan, and the smaller micro unit when you need finer detail.
