⚠️ These are theoretical maximums at 24/7 full-speed usage. Real-world usage is typically 1–5% of these values. See Mbps to GB/day for daily estimates.
Understanding how 100 Mbps scales from hourly to monthly — critical for data cap planning.
⚠️ Most ISP data caps are 1–1.25 TB/month. At 100 Mbps, you would hit a 1 TB cap in only ~22 hours of continuous full-speed usage.
Average household usage: ~30–50 GB/day (~1 TB/month)

💡 Quick math: Multiply your Mbps by 0.45 to get GB/hour. Or simply multiply MB/s by 3.6.
Understanding the relationship between Megabits per second and Gigabytes per hour.
Converting Mbps to GB/hr helps you understand your actual data throughput. ISPs advertise in Mbps but your experience depends on GB/hr.
Many applications and protocols specify bandwidth in GB/hr. Use this converter to match your network capacity to software requirements.
GB/hr = Mbps × 0.45. Apply × 0.45 to any Mbps value. For example: 100 Mbps = 45 GB/hr.
Memorize the factor: × 0.45. This lets you do instant conversions in your head whenever you see Mbps values.
Common questions about converting Mbps to GB/hr.
100 Mbps at full speed = 45 GB per hour. Formula: 100 × 3600 ÷ 8 ÷ 1000.
Yes! If you have a 1 TB/month cap, at 100 Mbps continuous you would hit it in ~22 hours of full-speed usage.
4K Netflix uses ~7 GB/hr, 1080p ~3 GB/hr. Much less than max speed because video is compressed.
No. Mbps (Megabits per second) measures instantaneous speed in bits, while GB/hour measures total data volume transferred over one hour in bytes. To convert: multiply Mbps by 0.45 to get GB/hour. The conversion accounts for both the bits-to-bytes division (÷ 8) and the seconds-to-hours multiplication (× 3,600).
500 Mbps = 225 GB per hour at maximum throughput. That is enough to download roughly 30 HD movies, 45,000 photos, or several large game installations every hour. Use our download time calculator for file-specific estimates.
1 Gbps (1,000 Mbps) transfers 450 GB per hour. That is 10,800 GB (10.8 TB) per day at full speed. In practice, a typical Gigabit household uses around 0.5–2 TB per month — a tiny fraction of the theoretical maximum.
Netflix data usage per hour: SD (480p): ~1 GB/hr. HD (1080p): ~3 GB/hr. 4K Ultra HD: ~7 GB/hr. HDR 4K: ~10 GB/hr. These are much lower than your maximum MB/s throughput because video is heavily compressed.
YouTube data usage per hour: 360p: ~0.3 GB. 720p: ~1.5 GB. 1080p: ~3 GB. 4K: ~12 GB. YouTube uses VP9/AV1 codecs which are more efficient than older codecs, but 4K content with HDR can use significantly more. Check your required streaming bitrate for content creation.
Yes, significantly. WiFi reduces your effective throughput compared to wired Ethernet. Wi-Fi 5 (802.11ac) delivers 50–70% of rated speed. Wi-Fi 6 (802.11ax) improves to 70–85%. Walls, distance, and competing devices further lower your actual GB/hour. For maximum data transfer, use a wired connection.
Yes. ISPs can and do throttle speeds for specific types of traffic (streaming, torrents, gaming) during peak hours or after exceeding data caps. This directly reduces your GB/hour. Common throttling targets: Video streaming (capped to 1.5–5 Mbps), P2P traffic (reduced by 50–90%), and post-cap speeds (often reduced to 1–3 Mbps). Use a VPN to bypass some throttling, but be aware VPNs add 10–30% overhead.
1,000 Mbps (1 Gbps) = 450 GB per hour. Per day that is 10,800 GB (10.8 TB). Per month at 24/7 full speed: 324 TB. In real-world usage, expect 60–85% of this due to protocol overhead, router limitations, and daily usage patterns.
It depends entirely on your internet speed. At 10 Mbps: 4.5 GB/hour. At 50 Mbps: 22.5 GB/hour. At 100 Mbps: 45 GB/hour. At 300 Mbps: 135 GB/hour. At 1 Gbps: 450 GB/hour. Use our data transfer calculator for custom time periods.
Mbps = Megabits per second (what ISPs advertise). MB/s = Megabytes per second (what downloads show). GB/hour = Gigabytes per hour (data volume over time). The relationship: 100 Mbps = 12.5 MB/s = 45 GB/hour. Bits (b) are 8× smaller than Bytes (B), and GB/hour simply multiplies MB/s by 3.6.
