#000000 → hsl(0 0% 0%)

Values are shown at full precision, so converting back gives exactly #000000. The rounded form is what you normally paste into CSS.

Step-by-step math

Every number below is computed from the input, nothing is looked up.

1. RGB ÷ 255
```
R = 0.0000
G = 0.0000
B = 0.0000
```

2. max, min, Δ

max = 0.0000
min = 0.0000
Δ = max − min = 0.0000

3. L
```
L = (max + min) / 2 = 0.0000 = 0.00%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.0000 = 0.00%

5. H

Δ = 0 → grey, hue is undefined (written as 0)

6. HSL
```
hsl(0.00 0.00% 0.00%)
```
