mg, g, kg
What are the others meant to represent?
h = hecto da = deca (had to look that one up) d = deci c = centi
×100, ×10, ÷10, ÷100, respectively
You'll know centi from centimetres. Decimetres are somewhat common because 1dm³ = 1L. Hectopascal is a common unit of pressure.
no one uses hg or dag or dg... wouldve been better to put kg, mg, ug, ng on here...
Nobody uses those in every day conversation.
They will be used in specific contexts, like measuring fluids with syringes where space is limited and accuracy needs to be high.
I had a running gag once with my cheese guy where i would order in hectograms. I probably found it more amusing than he did.
Your cheese guy? You may be doing life better than me.
Certain ones get used a lot, like centimeters and dekapascals.
