On cpu's there are sometimes hardware instructions to make this incredibly fast if you're willing to scale by powers of 2 (so maybe 1024ths of a meter instead of millimeters as the fixed point representation). On aarch64 for example VCVT takes the parameter fbits which determines (more or less) how big the divisor is in your conversion. Perhaps some the the GPU whiz's here might know of an equivalent instruction, and how to convince a toolchain to generate it
