More specifically, ''encumbrance'' (enc.) is a combination of the weight and clumsiness of gear measured in coin-weight equivalents (cn), where {{unit|cn|1}} equals approximately {{frac|10}} of a pound in weight and awkwardness. For example, a {{unit|lb|1|2}} wineskin filled with a quart of water/wine ({{unit|lb|2|v=~}}), would only ''weigh'' {{unit|cn|25|v=~}}, but has a total enc. of {{unit|cn|30}}.

==Other units==
A d20/D&D mile ({{unit|miD}}) is {{unit|feet|6,000}}, and thus apparently a fantasy equivalent to the {{unit|foot|6,076|v=~~}} nautical mile rather than the {{unit|foot|5,280}} land mile.
A nautical mile ({{unit|miN}}) is one minute of latitude ({{frac|60}}{{unit|deg|1}}), making Earth’s meridional circumference {{unit|miN|21,600}}. Since Earth is not a perfect sphere, the actual length of a minute of latitude varies between {{unit|m|1,813}} and {{unit|m|1,861}} with a ''de jure'' average of {{unit|m|1,852}} ({{unit|ft|6076.12|v=~~}}).
The original intent for the meter was to be one ten-millionth of 90° latitude, such that {{unit|km|40,000}} would equal Earth’s meridional circumference. The best measurements of the 1800s were slightly off and Earth’s actual m. circ. in standard meters is {{unit|km|40,008|v=~~}}.
From this one can extrapolate that a standard D&D fantasy world could be:
# a {{unit|miN|21,600}} ≈ {{unit|km|40,008}} m.circ. spheroid like Earth,
# a {{unit|miD|21,600}} ≈ {{unit|km|39,502}} m.circ. spheroid with {{abbr|2½%|2.4891%}} less surface area than Earth, or
# a {{unit|miD|21,600}} = {{unit|km|40,000}} m.circ. sphere with D&D feet/inches etc. {{abbr|1¼%|1.2598% • 1 D&D inch ≈ 25.72 ㎜}} longer than standard feet/inches.

Coins of Waterdeep

Nib
“Copper coin about the size of a thumbnail (1 nib = 1 common copper coin)”
If the example is ¹⁄₂″ side-to-side (thumbnail size), then it’s ⁵⁄₈″ on the diagonal, and the single-surface area is ∼.24 sq.in.
If the example is ³⁄₅″ side-to-side (fits inside taol), then it’s ³⁄₄″ on the diagonal, and the single-surface area is ∼.35 sq.in.
If the example is ³⁄₄″ side-to-side (²⁄₃ of a dragon), then it’s ¹⁵⁄₁₆″ on the diagonal, and the single-surface area is ∼.54 sq.in.
Shard
“Silver coin, slightly smaller than the nib (1 shard = 10 nibs)”
Taol
“Brass coin, about two inches square with a hole large enough for a nib to fit in (1 taol = 200 nibs)”
If the example is 2″ wide, then the hole diameter is ¾″, and the single-surface area is ∼3.4 sq.in.
Dragon
“Gold coin, half again as large as a nib (1 dragon = 100 nibs)”
If the example is ³⁄₄″ square (1¹⁄₂ × ¹⁄₂″ nib), then the single-surface area is ∼⁴⁄₉ sq.in.
If the example is ⁹⁄₁₀″ square (1¹⁄₂ × ³⁄₅″ nib), then the single-surface area is ∼²⁄₃ sq.in.
If the example is 1¹⁄₈″ square (1¹⁄₂ × ³⁄₄″ nib), then the single-surface area is ∼1 sq.in. (Same as standard round D&D coin.)
Sun
“Platinum coin, twice as large as a nib (1 sun = 1,000 nibs)”
Harbor Moon
“Platinum crescent inset with electrum, about three inches long with a hole large enough for a nib to fit in (1 harbor moon = 5,000 nibs)”
If the example is 3″ wide, then it’s 2½″ tall, with tips 2.2″ apart, a ¼″ square hole, and single-surface area of ∼4.5 sq.in.

Standard D&D coins

A standard [d20] coin weighs about a third of an ounce, so fifty coins weigh a pound.

Background

Original D&D—“Basic” through Rules Cyclopedia—coins have an encumbrance of ∼‌1⁄10 pound each.

More specifically, encumbrance (enc.) is a combination of the weight and clumsiness of gear measured in coin-weight equivalents (cn), where 1 𝖼𝗇 equals approximately ‌1⁄10 of a pound in weight and awkwardness. For example, a ‌1⁄2 lb wineskin filled with a quart of water/wine (∼ 2 lb), would only weigh ∼ 25 𝖼𝗇, but has a total enc. of 30 𝖼𝗇.
