Imperial, obviously: F(reedom)T(ons) and fractions thereof. 1FT is the amount of data that it takes to store the entire King James edition of the New Testament and the Bill of Rights as a PDF.

In America, you need a monthly subscription to use that system

As all your other measurements are based on the subjective measures of random people, I'd suggest using the amount of digits of pi a senior can remember in the time a new school shooting happens as a base, like a Bit. Then just multiply by a random amount for bigger sizes and prefix the name with random presidents names.

Those are units of discrete quantity, so couple, dozen, score, gross, grand, etc.: https://en.wikipedia.org/wiki/Non-numerical_words_for_quantities

A bit in Freedom units is 2 metric bits because it wouldn't be freedom units without unnecessary confusion. A metric bit is equivalent to a freedom unit lil'bit, because it's smaller than a bit. A bite (no relation to a byte) is 25 lil'bits because saying 25 ones and zeros outload is a mouthful. A hot dog is 4.2 bites or 105 lil'bits because that's how many bites it takes me to eat a hot dog. A hamburger is 6.4 bites because it takes more bites to eat. A double with cheese is 7.8 bites. A whole hog is 233 hot dogs. A stampede is 23146 hamburgers.

The Indians use Crore and Lakh

• A nugget: 1 bit
• A tendy: 1 byte
• A hot dog : 1 kb
• A hamburger: 1 mb
• A KFC bucket: 1 gb

1TB can be Recommended Chrome Ram?

TiB

One tebibyte equals 2^40 or 1,099,511,627,776 bytes.

I'm surprised there aren't more suggestions which use intentionally-similar abbreviations. The American customary system is rich with abbreviations which are deceptively similar, and I think the American computer memory units should match; confusion is the name of the game. Some examples from existing units:

• millimeter (mm) vs thou (mil)
• meter (m) vs mile (mi)
• kilo (k) vs grand (G)
• kilonewtons (kN) vs knots (kn)
• statute mile (m/sm) vs survey mile (mi) vs nautical mile (NM/nmi) vs nanometer (nm)
• foot (ft) vs fathom (ftm)
• chain (ch) vs Switzerland (ch)
• teaspoon (tsp) vs tablespoon (tbsp)
• ounce (oz) vs fluid ounce (fl oz) vs troy ounce (ozt) vs Australia (Ozzie)
• pint (pt) vs point (pt)
• grain (gr) vs gram (g)
• Kelvin (K) vs Rankine (R; aka "Kelvin for Americans")
• short ton (t) vs long ton (???) vs metric tonne (t) vs refrigeration ton (TR)
