How to convert millimeters to kilometers
Any physical quantity can be written as:
Q = nu , where n= numerical value and u = unit used
We know that:
1 mm = 0.000001 km
1 km = 1000000 mm
So, you can easily convert your quantity in mm to km by simply multiply it by 0.000001
Hence, general formula to convert mm to km:
p(km) = 0.000001 × p(mm), where p is the numerical value
For example:
Convert 15 mm to km
15 mm = 15 × 0.000001 km = 0.000015 km
About Millimetre (mm)
Name of unit: Millimetre
Abbreviation: mm
Unit system: metric system
Definition: Millimetre is the metric unit of length used to measure the length of very small objects or distances. In SI units, the fundamental unit of length is the metre and 'milli' is the latin word refers to the prefix of the metre which is equal to one thousandth i.e 0.001 ( 1 mm = 1/1000m ). Thus we can say that millimetre is one thousandth of a metre.
Uses of mm: Millimetre is the small unit of length. So , it is used to measure the length of very tiny objects like nib of a pen, a pencil or a needle , thickness of sheet or cloth etc . Miillimetre is also used various fields like physics, chemistry , medicines, mathematics etc for small measurements.
Countries that use CM: Millimetere is the metric unit of length, so it is used by all other countries around the world except the US, Liberia and Myanmar.
About Kilometer (km)
Name of unit: Kilometre
Abbreviation: km
Unit system: metric system
Definition: Kilometre is the metric unit of length used to measure the length of very large objects or distances. In SI units, the fundamental unit of length is the metre and 'kilo' is the Greek word refers to the prefix of the metre which is equal to thousand i.e 1000 ( 1 Km = 1000m ).
Uses: Kilometre is the larger unit of length is used to measure the lenght of roads , height of big buildings etc. It is also used in various fields like physics, chemistry , medicines, mathematics etc for large measurements.
Countries that use km: Kilometre is the metric unit of length, so it is used by all other countries around the world except the US, Liberia and Myanmar.
