minus-squareArve@lemmy.worldlinkfedilinkarrow-up0·3 months agoDon’t forget the most important US measurements of them all: 5.56, 7.62, 9, etc.
minus-squareKaryoplasma@discuss.tchncs.delinkfedilinkarrow-up0·3 months ago.308 is caliber in inches thus not metric.
minus-squareI'm back on my BS 🤪@lemmy.worldlinkfedilinkEnglisharrow-up0·3 months agowhy do they use decimal for imperial units?
minus-squareLiz@midwest.sociallinkfedilinkEnglisharrow-up0·3 months agoBecause even people who worked in imperial recognized that dealing with stupid fractions is stupid.
minus-squareThunderclapSasquatch@startrek.websitelinkfedilinkarrow-up0·3 months agoIt means the round fired by the gun is .308 inches in diameter, or 7.62mm. Gun caliber is measured in inches for Imperial.

minus-squareKaryoplasma@discuss.tchncs.delinkfedilinkarrow-up0·3 months agoBecause they couldn’t rationalize using fractions.

minus-squareI'm back on my BS 🤪@lemmy.worldlinkfedilinkEnglisharrow-up0·3 months agoso why don’t they write 1/1000 in then?
minus-squareCaptain Aggravated@sh.itjust.workslinkfedilinkEnglisharrow-up0·3 months agoBecause, unlike internet pendants, machinists have shit to do.
minus-squareMountaineer@aussie.zonelinkfedilinkEnglisharrow-up0·3 months ago.308 is 7.62, civilian measurement vs military (there’s actually implications related to pressures, sidewall thicknesses, machining tolerances, but yeah same same)
minus-squareKaryoplasma@discuss.tchncs.delinkfedilinkarrow-up0·3 months agoYeah, it’s generally safe to shoot 7.62 from a 308-chambered gun, but not the other way around.

Same for 5.56 and .223.
