The “Mebibytes” value used in this tool’s formula. Adjust it to see results update live.
MB = MiB × 1.048576.
1 MiB = 1,048,576 bytes. 1 MB = 1,000,000 bytes. Multiply MiB by 1.048576. A 700 MiB ISO is 734 MB on a decimal progress bar. That is why two windows never match.

- Bits to BytesEight bits make a byte. Networks advertise bits (Mbps). Disks advertise bytes. Divide bits by 8. A 1,000,000 bit dump is 125,000 bytes — not a megabyte of disk unless you meant megabits.
- 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.
- Megabits to MegabytesThe ISP sold you 100 Mbps. The download window shows MB/s. Divide by 8. 100 Mbps is 12.5 MB/s in a perfect vacuum. Real TCP, Wi-Fi, and VPN eat a slice. If you see 11 MB/s on a “100 megabit” line, you are fine.
- Megabytes to GigabytesDrive makers sell decimal GB (1,000 MB = 1 GB). Windows often shows GiB (1,024³). A “500 GB” disk showing 465 GB is not broken — it is two dictionaries. This page uses SI decimal: divide MB by 1,000.
- 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.

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.
