Values are shown at full precision, so converting back gives exactly #ffe4b5. 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. sRGB → linear

R: 255/255 = 1.00000 → 1.000000  (((x + 0.055) / 1.055)^2.4)
G: 228/255 = 0.89412 → 0.775822  (((x + 0.055) / 1.055)^2.4)
B: 181/255 = 0.70980 → 0.462077  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.852092
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.789631
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.597965

3. cube root

l′ = ∛0.852092 = 0.948045
m′ = ∛0.789631 = 0.924290
s′ = ∛0.597965 = 0.842478

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.92962
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.01012
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.06677

5. Oklab → OKLCH

C = √(a² + b²) = 0.06754
H = atan2(b, a) = 81.379°
L = 0.92962

6. OKLCH

oklch(0.92962 0.06754 81.379)
rounded: oklch(0.930 0.068 81.4)
