Gbps → TB / Day Egress
Sustained 1 Gbps equates to approximately 10.8 TB transferred per 24-hour period. This tool converts between network throughput (Gbps) and daily transfer volume (TB) for cloud egress cost modeling and CDN capacity planning.

| 0.1 | 32.4 | $2,754 |
| 1 | 324 | $26,798 |
| 5 | 1,620 | $133,488 |
| 10 | 3,240 | $263,088 |
| 40 | 12,960 | $1,049,088 |
| 100 | 32,400 | $2,620,488 |
Gbps → TB/Day: The Egress Equation
The conversion is straightforward: 1 Gbps sustained for 24 hours = (1 × 10⁹ bits/s × 86,400 s) ÷ (8 bits/byte × 10¹² bytes/TB) ≈ 10.8 TB/day. This assumes 100% link utilization — in practice, bursty traffic patterns, TCP slow-start, and inter-packet gaps reduce effective throughput by 10–30%.
For cloud egress planning, this is the single most important conversion to internalize. A 10 Gbps Direct Connect link can push up to 3,240 TB/month — at AWS standard egress pricing (~$0.09/GB after the first 10 TB), that's over $263,000/month in data transfer charges alone. Enterprises often discover this only after their first cloud bill shock. Budget egress capacity and costs with this tool before architecting cross-region or hybrid-cloud data pipelines.
