堯字節

堯字節；港澳嗰邊嗌堯位元組；全名係堯他位元組或堯他字節；簡稱YB，佢係一種資訊計量單位，依家通常用嚟標示網絡硬碟容量，又或者容量大嘅儲存媒介嘅容量時使用。據估算，2022年成個互聯網嘅容量總和唔超過800EB。響1公克DNA入面可以儲存360EB嘅信息量。

同其他儲存單位嘅換算 
1YB = 1,000 ZB
1YB = 1,000,000 (106) Eb
1YB = 1,000,000,000 (109) PB
1YB = 1,000,000,000,000 (1012) TB
1YB = 1,000,000,000,000,000 (1015) GB
1YB = 1,000,000,000,000,000,000 (1018) MB
1YB = 1,000,000,000,000,000,000,000 (1021) KB
1YB = 1,000,000,000,000,000,000,000,000 (1024) B

另外，堯字節成日都可以係堯比字節，換算公式係：
1YiB = 1,024 ZiB
1YiB = 1,048,576 (10242) EiB
1YiB = 1,073,741,824 (10243) PiB
1YiB = 1,099,511,627,776 (10244) TiB
1YiB = 1,125,899,906,842,624 (10245) GiB
1YiB = 1,152,921,504,606,846,976 (10246) MiB
1YiB = 1,180,591,620,717,411,303,424 (10247) KiB
1YiB = 1,208,925,819,614,629,174,706,176 (10248) B
