Kibibytes to Kilobytes Converter (KiB to KB)
KB = KiB × 1.024.
KiB is 1,024 bytes. KB here is 1,000 bytes. Multiply KiB by 1.024. RAM and old Windows file sizes think in kibibytes even when the UI says KB. This page is the handshake between those two lies.

- Kilobytes to MegabytesEmail attachments and tiny logs. SI: 1,000 KB = 1 MB. People still type 1,024 because of kibibytes. This page divides by 1,000. A 5,000 KB photo is 5 MB decimal, 4.77 MiB in Finder-old-speak.
- Bytes to KilobytesDivide bytes by 1,000 for SI KB. Old textbooks divided by 1,024 (KiB). A 2,048-byte packet is 2.048 KB decimal or 2 KiB. Pick the dictionary your protocol spec uses.
- Acres to HectaresUS farm ads in acres, EU paperwork in hectares. Divide acres by 2.471. Ten acres is 4.05 ha. A 160-acre quarter-section is 64.7 ha.
- Acres to Square FeetUS land: one acre is 43,560 ft², a chain-and-furlong leftover that refused to die. A quarter-acre lot is 10,890 ft². Multiply acres by 43,560. Soccer-field metaphors are not a survey.

Unit Converters
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.
