Binary number system is used now in some electronic computers, every number
being expressed by means of two digits — 0 and 1.
Concerning English units of measurements it should be said that it stands aside
from International Metric System. The International decimal system of measures (Met-
ric System) is based on the metre and kilogramme. Thus, distance and length are usu-
ally measured in millimetres, centimetres, metres, kilometres; mass is measured in
gramms, kilogrammes, centners and tons.
This Metric System (metre — kilogramme — second — MKS) was proposed by
France and was accepted universally in science by many countries. Its main advantage
is the decimal nature, i. e. all metric units can be divided into 10, 100, 1000 etc. parts.
And that is why all fracional measures may be expressed as decimals and they are cer-
tain to be manipulated much easier in mathematics.
The English System of measurements is much more complicated notwithstaning
the fact of accepting International Metric (decimal) System some twenty years ago. Up
till now the English System uses: foot, yard, and mile as units of distance and length;
ounce, pound and ton as units of weights and force.
This system is called Foot-Pound-Second (F.P.S.) and it is used in Great Britain
and the United States of America. But still the units of measurements in England and
USA are not always quite the same. For instance, British units include: barleycorn
(8.47 mm), line (2.12 mm), skein (109.7 m), rope (6.096 m), fathom (1.8 m), ell (1.14
m), pace (1.14 m) etc. and the American system of measures has not got them.
The numeral meaning of one and the same unit may be different: in Britain a ca-
ble's length — 219 metres, while in the USA it is 183 metres. The same difference
may be found in other units of measurement. So it is necessary to look up the numeri-
cal meanings of units in the English-Russian Polytechical Dictionary to distinguish
between British and American measures.
