Convert Bits to Exabits
Convert Bits (b) to Exabits (Ebit) instantly and accurately.
Conversion Formula
Ebit = b × 1.000000000e-18
About Bits
The bit (b) is the fundamental unit of digital information - a single binary digit: 0 or 1. Coined by John Tukey in 1948; formalised by Claude Shannon. Physically realised as transistor states (SRAM/DRAM), magnetic domains (HDD), charge levels in NAND flash (MLC=2, TLC=3, QLC=4 bits per cell). Shannon entropy: a coin flip = 1 bit; a card drawn from a 52-card deck ≈ 5.7 bits. 1 bit = 1/4 nibble = 1/8 byte.
About Exabits
An exabit (Ebit) = 10¹⁸ bits (SI). Global IP traffic ≈ 4.8 exabytes/month in 2022 = ≈38.4 Ebit/month. Netflix at peak consumes ≈15% of North American bandwidth, accumulating Ebits/year. All installed cross-Atlantic cable capacity ≈ 2,000 Tbit/s in 2024; 1 Ebit transits in ≈ 500 s at full utilisation. The Square Kilometre Array (SKA) will generate ≈ 7,200 Ebit/year of reduced data. 1 Ebit = 10¹⁸ bits = 125 PB.
