Pebibytes to Petabytes Converter (PiB to PB)
PB = PiB × (1024⁵ / 10¹⁵) ≈ × 1.12589991.
1 PiB = 1,024⁵ bytes = 1,125,899,906,842,624 bytes. 1 PB = 10¹⁵ bytes. Multiply PiB by 1.125899906842624. Cloud “petabyte” quotes often mean PB; file-system df -h often means PiB. The SI vs IEC scaler does the rest of the ladder.

A 5K is 5,000 meters, not 5 kilometers on the nose if your watch is sloppy. Divide meters by 1,000. Track races, building plans, and “how far was that hike” all live in this split.
Feet to Meters
Unit Converters
US height, ceiling height, and lumber still arrive in feet. Meter plans do not. One foot is exactly 0.3048 m — not “about a third.” Use this when a listing says 10 ft ceilings and the architect works in meters.
Inches to Centimeters
Unit Converters
Monitor diagonals, waist measurements, and photo prints still come in inches. Clothing charts in Europe come in cm. Multiply inches by 2.54. That factor is exact, not a kitchen guess.
