WEIGHTS, MEASURES, AND TEMPERATURES

As the metric system of weights and measures and the Centigrade measurement

of temperatures are employed in scientific work, the following tables

showing the English equivalents of those in most frequent use are given for

the convenience of those not already familiar with these standards. The

values given are approximate only, but will answer for all practical

purposes.

WEIGHT

===================================

Kilogram | kg. | 2-1/5 pounds

----------+-----+------------------

| | 15-1/2 grains

| | avoirdupois.

| | 1/28 of an ounce

Gram | gm. | avoirdupois.

-----------------------------------

CAPACITY

-----------------------------------

| | 61 cubic inches,

| | or a little more

| | than 1 quart,

Liter | l. | U. S. measure.

----------+-----+------------------

Cubic | | cc. 1/16 of a

centimeter| | cubic inch.

MEASURES OF LENGTH

==================================

METRIC |ENGLISH EQUIVALENTS

----------+---+-------------------

Kilometer |km.| 2/3 of a mile.

==================================

The next table gives the Fahrenheit equivalent for every tenth degree

Centigrade from absolute zero to the boiling point of water. To find the

corresponding F. for any degree C., multiply the given C. temperature by

nine, divide by five, and add thirty-two. Conversely, to change F. to C.

equivalent, subtract thirty-two, multiply by five, and divide by nine.
