The Conversion of Metric Into English Weights and Measures
The conversion of metric into English weights and measures can be readily accomplished by means of the following relationships:—
Measures of Length
1 metre = 100 centimetres = 39·37 inches.
1 foot = O·3381 metre.
Measures of Capacity
1 litre = 1,000 cubic centimetres = ·2209 gall.
1 gall. = 4·5436 litres.
Measures of Weight
1 kilogramme = 1,000 grammes = 2·205 lb.
1 gramme = 15·443 grains.
1 cwt. = 50·802 kilogrammes.
Centigrade and Fahrenheit Thermometer Scales
To convert temperatures expressed in Centigrade degrees to Fahrenheit degrees multiply by 9, divide by 5, and add 32.
To convert temperatures expressed in Fahrenheit degrees to Centigrade degrees subtract 32, multiply by 5, and divide by 9.
