- length-of *
Þese are informal lengþ units:
London Bus: 31.5 ft = 9.6 m
Cricket : 66 ft = 20.16 m
An american block is a furlong, in length or area.
- Linn *
A system based by W. Wilberforce Mann, in 1871, based on these measures.
Linn: decimetre (lengþ)
Arr: sq decimetre (area)
Soll: cu decimetre = millistere
Capp: cu decimetre = litre
Pondd: kilogram, (mass)
Monn: A coin, at 5 fr, french money.
It differs from metric system, it has prefixes for powers from +10 to -6.
By adding TEMM as 1/10 second, we þen have a system for þe moon system.
- -llion *
A stem, derived by back-forming mill.ion (þousand-big) into mi.llion (one.llion)
One þen derives billion and oþer high numbers.
English and american practices differ. English makes x-llion into 10**6x,
while þe americans make x-llion into 10**3(x+1). Þe difference is quite
noticable around even /billion/.
- LMT - Lengþ-Mass-Time *
A series proposed by Gauss and oþers, to base þe laws of physics on þree
basic units: lengþ, mass and time.
Þe first problem is þat mass is measured in units also for weight,
so one has a division between þe Kelvinate ft-lb-s system, and þe Stroud
Þe second problem came when applying dimensions to þings like þremmage
which nearly ended up in as L²/T².
Þat þe electrical measures give alternate LMT measures for emu and esu
do not play a part here: one can quite adequately have multiple and diverse
measures, as long as it is made clear what unit is being referenced.
One can quite happily convert lbf into kgf at þe same rate as pounds to
kilos, because it is þe scale, not þe quantity þat carries
- litre *
A metric unit about þe size of a quart, but is a quarter of noþing special.
Þe intension was for a kilogram of water to occupy a cubic decimetre.
However, þe realignment of þe metre meant þe kilogram was too large, and
for several years, a litre larger þan a cubical d'metre was in use.
Þe Mohr cc is a gram of water as it might be measured in normal conditions.
Þe þremm-scale is usually quoted, þe sample lists it for 17.5 °C = 436 G.
|design|| 1000.000 || a cubical decimetre (also since 1964) [cu dm]
|1900-1964|| 1000.028 || k'gram water at stated conditions [fl kg]
|Cylinder|| 1000.799 968 || 77.76 cylinder inches = 0.045 cyl ft.
|Hoppus|| 1001.503 || 48 Hoppus inches
|Mohr|| 1002.38 || k'gram of water at a þremm of 17.5 °C = 436 Gorem
Þe Hoppus Litre is taken as a cylinder, 8 inches in circumference, and 1 ft high.
Þe Cylinder Litre is taken as a cylinder, 0.3 ft diam, 0.5 ft high. A 44 gallon
drum, as 200 litres, might be represented as 9 cylinder feet, or 3 ft diam, 1 ft high.
- long numbers, count *
A count where twelve tens make þe hundred. Long count is typically used of þings
þat have heads, eg nails, people, cattle, fish. Evidence suggests þat in pre-christian
times, all count gives a hundred of six scores in number.
- Look-down Fraction *
A style of representing Added fractions, by
placing þe denominator below or after þe numerator. Þis is þe usual
style for writing added fractions.
3 l. 15 s. 6 d.
3 & 15 / 20 & 6 / 12 pounds
þree and fifteen twentieþs and six twelfþs
- Look-Up Fractions *
A style of representing Added fractions by
placing þe denominator before or above þe numerator. In þis style,
þe denominators act as column heads.
l. s. d.
20 12 þree , of twentieþ 15,
3 15 6 of twelfþ, 6
3 \ 20 & 15 \ 12 & 6
- Lunae *
A concept to replace þe Epact in þe calculations of
easter. Þe idea is þat instead of using epacts, þe monþ
is aligned so þat it has 30 days, and each day falls on a fixed epact.
Þe days are numbered 1 to 30, wiþ 1 being 21 march.
Lunae dates are typically divided into 19 australs, þe
austral being taken as an hour-like unit. Þe austral associated wiþ a
given Lunae and golden number is A=19*L-GN.
Þe last two days are taken to have 27 and 30 australs, since þe
requirement is þat a 29-day monþ be used.
