Metric units are the universally excepted
units around the world (except for the US).
They are the easiest to convert.

Metric Unit Examples:
 meters
 liters
 grams
Base Units – all
other metric
units are based
off of these
(km, cm, ml, kg)




1 km= 1000 m
100 cm= 1 m
1000 mm = 1 m
10 mm = 1 cm
These also work for liters and
grams. Just replace the base
unit (m) with a (g) or (l).

Length:
12 inches (in) = 1 foot (ft)
3 feet = 1 yard (yd)
5280 feet = 1 mile (mi)
Weight:
16 ounces (oz) = 1 pound
(lb)
2000 lb = 1 ton
Capacity:
3 teaspoons (tsp) = 1 tablespoon (tbsp)
16 tbsp = 1 cup (c)
8 ounces (oz) = 1 c
2 c = 1 pint (pt)
2 pt = 1 quart (qt)
4 qt = 1 gallon (gal)

A mathematical way to convert one unit to
another. This works for metric units and nonmetric (English) units.

This works by taking the unit you are given
and multiplying it by a conversion factor.
A unit conversion factor is a fraction whose
numerator and denominator are equivalent
measures. Some common unit conversion factors
are given below. You can also use the reciprocal of
these.

Given
100 cm
1m
For meters to cancel out,
meters in the conversion
factor must be on the
opposite side of the fraction
(fence).

= 300cm
Multiply every number on top
of the fence and divide by the

In the cases when used to describe data storage, bits/bytes are
calculated as follows:
1 byte = 8 bits
1 kilobyte (K / Kb) = 1,024 bytes
1 megabyte (M / MB) = 1,024 kilobytes
1 gigabyte (G / GB) 1,024 megabytes
1 terabyte (T / TB) = 1,024 gigabytes
A bit or binary digit is the basic unit of information in computing and
telecommunications; it is the amount of information that can be stored by
a digital device or other physical system that can usually exist in only two
distinct states.
