TABLE OF KILOMETRES AND MILES.
1 kilometre = 1,000 metres = 1,093 yards = 5/8 mile, as nearly as possible, without employing decimals; but at this computation the kilometre gains 11 yards, 40 kilometres gain 1/4 mile, and 160 kilometres gain 1 mile. This gain has been deducted in the following table, and all fractions less than 1/4 omitted:—

COMPARISON TABLE OF THE CENTIGRADE AND FAHRENHEIT THERMOMETERS.
1° Centigrade = 1-4/5 Fahr.; 5° Cent. = 9° Fahr. It must be understood that, as the freezing-point of Centigrade is Zero and of Fahrenheit 32°, these 32° must be taken into account in all calculations above freezing-point: thus +5° Cent. are equivalent to a temperature of 41° Fahr.
