Baud Rate Calculator

Your details

Select the formula that matches your available data. "Bit rate to baud rate" is the most common starting point.
Unit for the bit rate value you enter.
The raw data rate in bits per second (before symbol encoding).
The number of bits each transmitted symbol carries. Binary (NRZ) = 1 bit per baud, used by UART and RS-232.
Baud rateStandard speed
115,200baud

Symbol rate - number of distinct symbol changes per second

Bit rate115,200bps
Bits per symbol1
Symbol period8.6806us
Equivalent frequency115,200Hz
Nyquist bandwidth57,600Hz
Baud rate (baud)115,200
Bit rate (bps)115,200
Nyquist BW (Hz)57,600

Baud rate: 115.200 kbaud (bit-rate-to-baud mode).

  • Each symbol lasts 8.68 us.
  • The Nyquist minimum channel bandwidth is 57.60 kHz.

Next stepFor UART serial links (Arduino, Raspberry Pi), use 115200 baud with Binary modulation to stay within standard hardware limits. Pick higher modulation orders only for RF or cable links designed for it.
