Decimal (Base 10) vs. Binary (Base 2)

In high-capacity systems, Terabits to Gigabits calculations can differ by calculation standards:

Decimal (Base 10): Uses metric units (1 Tb = 1,000 Gb = 1,000 Gigabits). This is standard for modern fiber-optic network infrastructure and backbones.
Binary (Base 2): Uses base-2 power units (1 Tib = 1,024 Gib = 1,024 Gigabits). Standard for server clustering and storage area networks (SAN) allocation metrics.
