Como usar (3 passos)
- Escolha o que deseja resolver: tempo de transferência (tamanho + velocidade), velocidade de transferência (tamanho + tempo) ou tamanho de dados (velocidade + tempo).
- Informe os dois valores conhecidos com suas unidades. Ative o fator de eficiência se quiser considerar overhead (por exemplo, 80%).
- Resultados update automatically with conversions. Use “Copiar URL” to Compartilhar exactly the same scenario.
Seconds in the display are rounded up; sizes and speeds are rounded to 2 decimals.
Entradas
Fill in any two fields (data size, transfer speed, transfer time). Keep units consistent with your entry: b = bit, B = byte (1B = 8b). Decimal (GB) and binary (GiB) units are both supported.
Resultado
Transfer time Resultado
Estimated transfer time
1B = 8b. Decimal units use powers of 1000; binary units use powers of 1024.
Como é calculado
- Formula: data size = transfer speed × time. When solving for speed or time, we just rearrange this equation.
- All Entradas are converted to bits and seconds internally. Decimal units (GB) and binary units (GiB) are handled separately.
- If efficiency is on, effective speed = nominal speed × efficiency%. Use this to estimate protocol overhead or real-world loss.
- Seconds are rounded up for HH:MM:SS. Sizes and speeds are rounded to 2 decimals in the display.
- Real-world speeds fluctuate. Treat the Saída as an estimate, not a guarantee.
Perguntas frequentes
How do you handle bits vs bytes and GB vs GiB?
We convert everything to bits (b) and seconds, then back to your chosen units. 1 byte = 8 bits. GB/MB use 1000 steps, while GiB/MiB use 1024.
What does the efficiency factor change?
When enabled, effective speed = nominal speed × efficiency%. Lower efficiency increases the estimated time or required speed. Leave it off to treat your Entrada speed as fully usable.
Posso enter time as HH:MM:SS?
Yes. Choose the split field option for hours, minutes, and seconds, or use a single total time with seconds, minutes, hours, or days. Displayed seconds are always rounded up.
