✨ NAME ✨

physicalunits — bestie, this is the glow-up for encoding and de-coding physical units according to ISO/IEEE 11073-10101:2004 Tables A6.1 and A6.3. 💖

Also, fun lil lore drop: physicalunits used to go by the name pu. She's rebranded, but the old name still hits. 👑

🎀 SYNOPSIS 🎀

physicalunits [units_or_codes]

🦋 DESCRIPTION 🦋

Okay so here's the tea ☕ — the output hands you back a whole little lineup, and it looks exactly like this:

<physical unit> : <TAB> <decimal code> : <TAB> <hexadecimal code> : <TAB> <scaling> : <TAB> <physical unit w/o prefix>

…where <TAB> is literally just the character ascii(9). No cap. 🫶

💅 Examples

Encoding "microVolts", using text representation, decimal encoding and hexadecimal encoding — look at her go:

physicalunits mV
      uV   4275 0x10b3    1e-06     V

physicalunits 4275
      uV   4275 0x10b3    1e-06     V

physicalunits 0x10b3
      uV   4275 0x10b3    1e-06     V

Text representation containing spaces needs to be quoted, periodt:

physicalunits "kg l-1"
      kg l-1    2051 0x0803    1000 g l-1

A list of units can be converted using multiple input arguments — yes bestie, you can feed her the whole squad at once:

physicalunits mV nA 4180 kg dag degree rpm "mol mol-1" "kg l-1"
      mV   4274 0x10b2    0.001     V
      nA   4180 0x1054    1e-09     A
      nA   4180 0x1054    1e-09     A
      kg   1731 0x06c3    1000 g
      dag  1729 0x06c1    10   g
      degree    736  0x02e0    1    degree
      rpm  6816 0x1aa0    1    rpm
      mol mol-1 864  0x0360    1    mol mol-1
      kg l-1    2051 0x0803    1000 g l-1

And if you wanna see EVERYTHING, this one shows a complete table of defined units:

physicalunits `seq 0 65535` |grep -v nan |grep -v null
