GENERAL INFORMATION

METRIC CONVERSIONS

METRIC CONVERSIONS

Metric conversions are making life more difficult for the

mechanic. In addition to doubling the number of tools required,

metric-dimensioned nuts and bolts are used alongside English

components in many new vehicles. The mechanic has to decide which tool

to use, slowing down the job. The tool problem can be solved by trial

and error, but some metric conversions aren’t so simple. Converting

temperature, lengths or volumes requires a calculator and conversion

charts, or else a very nimble mind. Conversion charts are only part of

the answer though, because they don’t help you "think" metric, or

"visualize" what you are converting. The following examples are

intended to help you "see" metric sizes:

LENGTH

Meters are the standard unit of length in the metric system.

The smaller units are 10ths (decimeter), 100ths (centimeter), and

1000ths (millimeter) of a meter. These common examples might help you

to visualize the metric units:

* A meter is slightly longer than a yard (about 40 inches).

* An aspirin tablet is about one centimeter across (.4 inches).

* A millimeter is about the thickness of a dime.

VOLUME

Cubic meters and centimeters are used to measure volume, just

as we normally think of cubic feet and inches. Liquid volume

measurements include the liter and milliliter, like the English quarts

or ounces.

* One teaspoon is about 4 cubic centimeters.

* A liter is about one quart.

* A liter is about 61 cubic inches.

WEIGHT

The metric weight system is based on the gram, with the most

common unit being the kilogram (1000 grams). Our comparable units are

ounces and pounds:

* A kilogram is about 2.2 pounds.

* An ounce is about 28 grams.

TORQUE

Torque is somewhat complicated. The term describes the amount

of effort exerted to turn something. A chosen unit of weight or force

is applied to a lever of standard length. The resulting leverage is

called torque. In our standard system, we use the weight of one pound

applied to a lever a foot long, resulting in the unit called a foot-

pound. A smaller unit is the inch-pound (the lever is one inch long).

Metric units include the meter kilogram (lever one meter long

with a kilogram of weight applied) and the Newton-meter (lever one

meter long with force of one Newton applied). Some conversions are:

* A meter kilogram is about 7.2 foot pounds.

* A foot pound is about 1.4 Newton-meters.

* A centimeter kilogram (cmkg) is equal to .9 inch pounds.

PRESSURE

Pressure is another complicated measurement. Pressure is

described as a force or weight applied to a given area. Our common

unit is pounds per square inch. Metric units can be expressed in

several ways. One is the kilogram per square centimeter (kg/cm ).

Another unit of pressure is the Pascal (force of one Newton on an area

of one square meter), which equals about 4 ounces on a square yard.

Since this is a very small amount of pressure, we usually see the

kiloPascal, or kPa (1000 Pascals). Another common automotive term for

pressure is the bar (used by German manufacturers), which equals 10

Pascals. Thoroughly confused? Try the examples below:

* Atmospheric pressure at sea level is about 14.7 psi.

* Atmospheric pressure at sea level is about 1 bar.

* Atmospheric pressure at sea level is about 1 kg/cm .

* One pound per square inch is about 7 kPa.
