Download Time on a 1 Gbps Connection
Calculate Gigabit internet download times. 1 Gbps (1,000 Mbps) delivers ultra-fast download performance across all devices.
Quick Answer: On a 1 Gbps (Pure Fiber Optic (GPON/XGS-PON) direct to the premises.) connection, a 10 GB file finishes in and a 50 GB game takes under standard real-world network conditions.
How Download Time Is Calculated
Time = (File Size in bits) / (Speed in bits/sec × 0.90)To calculate transfer times at 1 Gbps, divide file size in Megabits by 1000 Gbps.
Convert to Bits
Multiply file size in Bytes by 8 to get total bits: 10 GB × 8,000,000,000 bits
Apply Speed & Overhead
Multiply network speed by real-world efficiency (typically 90% due to TCP/IP packet headers): 1 Gbps × 0.90
Divide to Find Duration
Divide total bits by effective throughput: 13 min 20 sec (theoretical) / 14 min 49 sec (with 90% real-world efficiency)

Frequently Asked Questions
What is 1 Gbps in MB/s?
1 Gbps equals 125 MB/s theoretical write speed (1,000 ÷ 8). In real-world TCP throughput, expect roughly 112 to 118 MB/s.
How fast will a 100GB game download on 1 Gbps?
On a 1 Gbps connection with 90% efficiency, a 100GB game finishes downloading in approximately 14 minutes and 49 seconds.
