Constant ckb_types::core::tx_pool::DEFAULT_BYTES_PER_CYCLES

pub const DEFAULT_BYTES_PER_CYCLES: f64 = 0.000_170_571_4_f64;

Equal to MAX_BLOCK_BYTES / MAX_BLOCK_CYCLES, see ckb-chain-spec. The precision is set so that the difference between MAX_BLOCK_CYCLES * DEFAULT_BYTES_PER_CYCLES and MAX_BLOCK_BYTES is less than 1.
