How to convert kg to n 1n = how many kg?

How to convert kg to n 1n = how many kg?

Your question is wrong
The cow is the unit of force, the kilogram is the unit of mass, they have different principles, their dimensions are different, they can not be converted
1kg*m/s=9.8n
1n=1/9.8kg*/s

What is the conversion relationship between weight unit, G, Mg, UG, PG, ng

1g ＝1000mg
1mg＝1000μg
1μg＝1000ng
1ng＝1000pg
(NG is larger than PG)

What is the conversion relationship between weight unit, G, Mg, UG, PG, ng?

1g = 1000mg 1mg = 1000 μ G 1 μ g = 1000ng 1ng = 1000pg (NG is larger than PG)

Xiao Ming has prepared a birthday gift for his mother. The picture shows the gift box. The length, width and height are 15cm, 10cm and 8cm respectively. Now tie the box with ribbon (as shown in the picture), and the joint length is 18cm. How many centimeters of ribbon do you need?

15 × 2 + 10 × 2 + 8 × 4 + 18, = 30 + 20 + 32 + 18, = 100 (CM), a: a total of 100 cm ribbon is required

On the density and volume mass of matter
If the density of a piece of steel is 7.8 * 10 3kg / M and the measured gas mass is 39kg, its volume is_____ If 1 / 3 of M is cut off, the density of the remaining part is 0_______ kg/m 3.

39/(7.8*10^3)=0.005(m³)
7.8*10^3kg/m^3

20.1 cubic decimeter = () ml

20.1 cubic decimeter = (20100) ml

There is a small gift box, which should be tied with ribbon. The knot is 10cm. How long is the ribbon? 15cm long, 9cm wide, 8cm high

100cm

How to calculate volume for density and mass in Physics
On April 29, 2009, Chongqing Chaotianmen Yangtze River Bridge, which is the first in the world, is just passing through. The main length of the bridge is 932m, and the steel used for the whole bridge is 4.6 × 10 ^ 7kg. How much is the total volume of steel used for the bridge? (density P steel = 7.9 × 10 ^ 3kg / m ^ 3) how long does it take for the pedestrian to pass through the main bridge if the walking speed of the sidewalk on the bridge is about 1.2m/s?

①V=m/p=4.6×10^7kg/7.9×10^3kg/m^3=5.82×10^3m^3
②t=s/v=932m/1.2(m/s)=776.67s

100 square decimeters=______ Square meter=______ Square centimeter

100 square decimeter = 1 square meter = 10000 square centimeter
