Drafting/Conversion Table of English Linear Measurements into Metric

The metric is now the official system of measurements for sizes and weights in the Philippines. At this writing, however, lumber, shoes, paper, and machine parts are still measured by the English system. Since it will take time to metricize all existing English measurements, the conversion table is provided below to help students adjust themselves to the transition. The metric equivalent of the English linear measurements are printed in decimal figures and are mostly in fractions of a meter. To read these fractional measurements which are given in decimal figures, it is suggested that the following simple rule be followed: All numbers at the left side of the decimal point are in meters; the first two numbers to the right of the decimal point are in centimeters; the third number to the right of that is in millimeters; and the rest of the numbers to the right of the third number are a fraction of a millimeter. For example, 1.016 reads: one meter, one centimeter, and 6 millimeters. Similarly, 5.55525 is read as 5 meters, 55 centimeters, and 5 1/4 millimeters. The last two numbers, or 25, is 1/4 of a millimeter. To find the equivalent of 3 1/8", for instance, just add the fractional metric equivalent of 1/8" to the metric equivalent of 3 inches. In this case, we have 1/8" = 0.0032 3" = 0.0762 0.0794 which reads: seven centimeters, nine millimeters, and 4/10, or 2/5, of a millimeter Table I Inches To Meter Inch/InchesMeterInchesMeter 1/320.0008130.3202 1/160.0016140.3556 1/80.0032150.381 3/160.0047160.4064 1/40.0063170.4318 5/160.0079180.4572 3/80.0095190.4826 7/160.0112200.508 1/20.0127210.5334 9/160.0142220.5588 5/80.0158230.5842 11/160.017424(2'-0")0.6096 3/40.019250.635 13/160.0205260.6604 7/80.022270.6858 15/160.0237280.7112 10.0254290.7366 20.0508300.762 30.0762310.7874 40.1016320.8128 50.127330.8382 60.1524340.8636 70.1778350.889 80.203236(3'-0")09144 90.2286370.9398 100.254380.9652 110.2794390.9906 12(1'-0")0.3048401.016 Table II Feet To Meters FeetMetersFeetMeters 10.3048144.2672 20.6096154.5720 30.9144164.8768 41.2192175.1816 51.5240185.4864 61.8288195.7912 72.1336206.0960 82.4384216.40 92.7432226.71 103.0480237.01 113.3528247.32 133.9624 Table III Inches To Millimeters Inch/InchesMillimetersInch/InchesMillimeters 1/320.821/3216.7 1/161.611/1617.5 3/322.423/3218.3 1/83.23/419.1 5/324.025/3219.9 3/164.813/1620.7 7/325.627/3221.5 1/46.47/822.3 9/327.129/3223.1 <tr> 5/167.915/1623.9 11/328.731/3224.7 3/89.5125.4 13/3210.3250.8 7/1611.1376.2 15/3211.94101.6 1/212.75127.0 17/3213.56152.4 9/1614.37177.8 19/3215.18203.2 5/815.99228.6 10254.0 11279.4 12304.8 13320.2 14355.6 15381 16406.4 17431.8 18457.2 19482.6 20508 21533.4 22558.8 23584.2 24609.6 Table IV Miscellaneous Lengths EnglishMetric 1 mile1.609 kilometers 1 yard(3 ft)0.9144 meter 3.28 ft1 meter 39.37 inches1 meter 1 inch2.54 centimeters
