Mbps ↔ MB/s ↔ Gbps कन्व्हर्ट करा आणि प्रत्यक्ष जगातील ओव्हरहेड व फाइल प्रीसेट्ससह (4K मूव्ही, OS इन्स्टॉल, गेम पॅच) कोणत्याही इंटरनेट स्पीडवर कोणत्याही फाइल आकारासाठी डाउनलोड वेळ काढा.

1 बाइट = 8 बिट्स. ISP मेगाबिट्स प्रति सेकंद (Mbps) मध्ये जाहिरात करतात; फाइल्स मेगाबाइट्स (MB) मध्ये असतात. MB/s = Mbps ÷ 8. वेळ = फाइल आकार ÷ थ्रूपुट. आम्ही दशांश पद्धत (1 GB = 1 000 MB) वापरतो कारण स्टोरेज आणि ISP मार्केटिंग SI प्रीफिक्स फॉलो करतात.
प्रत्यक्ष जगातील ओव्हरहेड (~10%) TCP / IP हेडर्स, रीट्रान्समिट्स आणि अनियमित सर्व्हरमुळे होतो. सैद्धांतिक वेळ × 1.111 ≈ प्रत्यक्ष वेळ.
Download time = file size in bytes divided by (bits per second / 8). Every unit here is decimal SI rather than binary: 1 Mbps is 1,000,000 bits per second and 1 GB is 1,000,000,000 bytes, matching how ISPs advertise speed and how drives are labelled. Tick Apply ~10% real-world overhead and the time is multiplied by 1.111, the reciprocal of 90% goodput, covering TCP and IP headers, retransmits and bursty servers.
The speed Unit field is the one people get wrong. Kbps, Mbps and Gbps are bits; KB/s, MB/s and GB/s are bytes, and the eightfold gap between them is the whole reason this tool exists. Defaults are 100 Mbps against a 5 GB file, which comes out at 6m 40s. Six presets fill the file size in: MP3 song (5 MB), 1080p movie (5 GB), 4K movie (25 GB), OS install (5 GB), Game patch (50 GB) and AAA game (100 GB).
This is a straight division, so it assumes you hold your full advertised line rate for the entire transfer. It models nothing about the source server's own upload cap, Wi-Fi loss, evening congestion, disk write speed, or TCP slow start at the beginning of a connection. The overhead option is a single flat 10% allowance rather than a protocol simulation, and the conversion table always lists both the theoretical and the padded time regardless of the checkbox.
12.5 MB/s, because there are eight bits in a byte and the tool uses decimal megabits. The conversion table prints that directly, alongside the same speed expressed in Mbps and Gbps, whichever unit you originally typed in.
At 100 Mbps, about 2h 13m theoretically, or roughly 2h 28m once the 10% overhead allowance is applied. The AAA game (100 GB) preset fills the file size in for you, so you only need to set your line speed.
1,000. Kilo, mega, giga and tera are all powers of ten here, for both speeds and file sizes, because ISPs and drive manufacturers use SI prefixes. Your operating system may report the very same file as a smaller number of gigabytes.
The maths assumes your full line rate end to end. In practice the source server may throttle you, Wi-Fi and peak-time congestion cut throughput, and connections need time to ramp up. The overhead checkbox only covers protocol overhead, around 10%.
It is a fixed reference point: how long a single gigabyte takes at whatever speed you entered, independent of the file size field. Useful for mental arithmetic, since you can multiply it by however many gigabytes you actually need to move.
