数字存储 Converter
免费数字存储转换器, 即时换算字节、KB、MB、GB、TB 和 PB
使用 OmniConverter 免费在线存储换算器在比特、字节、KB、MB、GB、TB 和 PB 之间即时换算。1 GB 等于 1,024 MB，1 TB 等于 1,024 GB，1 PB 等于 1,024 TB。无论你是比较硬盘大小还是计算数据传输限制，都能获得即时结果。
使用方法
通过三个简单步骤进行转换。
输入数字存储值
在「输入值」字段中键入要转换的存储大小。例如，输入 1024 转换 1024 兆字节，或输入 500 转换 500 千兆字节。
选择源存储单位与目标单位
在左侧选择输入单位（例如比特、字节、千字节、兆字节、千兆字节、太字节、拍字节），在右侧下拉菜单中选择所需输出单位。
获取转换后的文件或存储大小
结果使用二进制（基于 1024）计算立即显示。非常适合比较硬盘容量、云存储计划、文件大小、内存以及网络数据传输容量。

实际应用场景
中国移动、中国联通和中国电信提供5G套餐，包含30-300GB不等的流量。宽带入户速度从100M到1,000M（千兆）不等。一个常见的问题是，1Gbps的宽带的实际下载速度是多少, 理论值128MB/s，但实际受限于服务器和线路。手机存储容量从128GB到1TB，但系统和应用占了起码30GB。一张iPhone 48MP的高清照片约5-10MB，一分种4K视频约400-500MB。视频创作者在后期制作中，一个Premiere Pro项目文件加素材可达数百GB。百度网盘、阿里云盘等云存储服务提供2TB免费/付费空间。企业用NAS（群晖、威联通）配置多TB存储。DVD单层4.7GB，蓝光25-50GB，UHD蓝光100GB。Windows系统中1GB=1,024MB（二进制），而硬盘厂商使用1GB=1,000MB（十进制），导致1TB硬盘在系统中只显示931GB。服务器的DDR5内存单条可达64GB。

常见换算问题的快速解答
1GB等于多少MB？+
1GB = 1,024MB（二进制）。硬盘厂商有时用1GB = 1,000MB（十进制）。
流量套餐怎么选？+
中国三大运营商：移动、联通、电信。日常使用约20-50GB/月。刷抖音约1GB/小时。
如何将MB换算成GB？+
MB除以1,024即可得到GB。
比特和字节的区别？+
1字节（Byte）= 8比特（bit）。网速用Mbps（兆比特/秒），存储用MB（兆字节）。
5G网速有多快？+
中国5G理论峰值可达10 Gbps（约1,250 MB/s），实际约500 Mbps-1 Gbps。
500M宽带够用吗？+
500M宽带下载约62.5 MB/s，满足4-6人家庭使用。1000M（1G）适合重度用户。
如何将Gbps换算成Mbps？+
Gbps乘以1,000即可得到Mbps。
