No. HP 44 and HB 130 are intended for regulation of retail trade which requires precisions of only three significant digits. MP233 gives equivalents to many more digits. For example: 1 avdp. dram = 0.001 771 845 195 312 5 kilogram, quoted from page 11. I did not take the trouble to verify this number by way of 1 dram = 1/256 pound. Is it exact or rounded? I don't know. Gene.
