This document discusses units of length and how to convert between different units. It defines length and different standard units including meters, centimeters, millimeters, and kilometers. It provides conversion formulas and examples for converting between meters and kilometers, centimeters and meters, millimeters and centimeters, and liters and milliliters. An activity at the end asks the reader to do conversions between these different units.

LENGTH

2.  Length is the term used for
identifying the size of an object or
distance from one point to Length is
a measure of how long an object is
or the distance between two points. It
is used for identifying the size of an
object or distance from one point to
another. The length of an object is its
extended dimension, that is, its
longest side.

3. Different units of length
The standard unit of length based on
the metric system is a meter (m).
According to the length that needs to
be measured, we can convert a
meter into various units like
millimeters (mm), centimeter (cm),
and kilometer (km).

4. Centimeters and millimeters help
measure smaller lengths and
meters and kilometers help
measure larger lengths like
distance. For example, the length of
the pencils can be calculated in
centimeters (cm), while kilometers
can measure the distance between
two buildings or places.

6. Convert km to m
- To convert a kilometer
measurement to a meter
measurement, multiply the
length by the conversion
ratio.

7.  Since one kilometer is equal
to 1,000 meters, you can use
this simple formula to convert:
meters = kilometers × 1,000
The length in meters is equal to
the kilometers multiplied by
1,000.

8. For example, here's how to
convert:
5 kilometers to meters using
the formula.
5 km = (5 × 1,000m) =
5,000 m

9. km = meters ÷ 1,000
For example, here's how to
convert 5,000 meters to
kilometers using the formula
above.
5,000 m = (5,000 ÷ 1,000) =
5 km

10. centimeters = meters × 100
For example, here's how to
convert 5 meters to
centimeters using the formula
above.
5 m = (5 × 100) = 500 cm

11. meters = centimeters ÷ 100
For example, here's how to
convert 500 centimeters to
meters using the formula
above.
500 cm = (500 ÷ 100) = 5 m

12. mm = cm x 10
For example, here's how to
convert 5 mm to cm using the
formula above.
5 mm = (5 x 10) = 50 cm

13. cm = mm ÷ 10
For example, here's how to
convert 50 mm to cm using
the formula above.
50 cm = (50 ÷ 10) = 5 mm

14. 8,000m= _____ km

15. Liters=milliliters÷ 1,000
For example, here's how to
convert 5,000 milliliters to
liters using the formula above.
5,000 ml = (5,000 ÷ 1,000) = 5 l

16. milliliters = liters × 1,000
For example, here's how to
convert 5 liters to milliliters
using the formula above.
5 l = (5 × 1,000) = 5,000 ml

17. Activity:
1. 3m= 300cm
2. 500cm= 5m
3. 4km= 4,000m
4. 12cm= 120mm
5. 240mm= 24cm
6. 80m= 8,000cm
7. 700cm= 7m
8. 2km= 2,000m
