Gigabits per second
The “Gigabits per second” value used in this tool’s formula. Adjust it to see results update live.
GB/s = Gbps ÷ 8.
10 GbE and fiber quotes. Divide Gbps by 8. 10 Gbps is 1.25 GB/s — faster than many disks. A “gigabit” home plan is 1 Gbps = 0.125 GB/s, not a gigabyte a second. Sales teams enjoy that confusion.

When to use this Gigabits to Gigabytes
Common use cases
- 10 GbE and fiber quotes. Divide Gbps by 8. 10 Gbps is 1.25 GB/s — faster than many disks. A “gigabit” home plan is 1 Gbps = 0.125 GB/s, not a gigabyte a second. Sales teams enjoy that confusion.
- Sanity-check with this scenario: 1 Gbps → 0.125 GB/s (125 MB/s). 40 Gbps → 5 GB/s.
- The relationship is: GB/s = Gbps ÷ 8.

- Gibibytes to Gigabytes1 GiB = 2³⁰ bytes. 1 GB = 10⁹ bytes. Multiply GiB by 1.073741824. A 931 GiB “1 TB” disk is the classic unboxing surprise: 1,000,000,000,000 bytes ≈ 931 GiB.
- Gigabytes to TerabytesNAS shelves and video libraries. Divide GB by 1,000 for decimal TB. 4,000 GB is 4 TB on the box. macOS 10.12+ also uses decimal; older Windows “TB” was often tebibytes. Know which UI you are reading.
- 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.
- Appliance Running CostCost = watts × hours / 1000 × $/kWh. A 1,500 W space heater for 4 hours at $0.16/kWh is $0.96. The supply rate on the bill is the one that matters, not a national average.

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.
