Length unit conversion
Rice of 1 kilometre =1000 decimetre of 1 meter of =10
1 decimetre =10 centimeter 1 meter of =100 centimeter
Millimeter of 1 centimeter of =10
Area unit conversion
Hectare of =100 of 1 square kilometre
Square metre of 1 hectare =10000
Decimetre of square of =100 of 1 square metre
Square of =100 of 1 square decimetre centimeter
1 square centimeter =100 square millimeter
Body (look) accumulate unit conversion
Cubic decimetre of 1 stere =1000
=1000 of 1 cubic decimetre is cubic centimeter
=1 of 1 cubic decimetre rises
1 cubic metre centimeter =1 milliliter
1 stere =1000 rises

Commonly used graph calculates elementary school maths formulary:
1, square
Side of A of area of C circumference S is long
Circumference = edge grows × 4
Area = edge grows by the side of long ×
C=4a
S=a × A S=a2
2, square body
Arris of V bulk A is long
Arris of long × of arris of long × of arris of 6 bulk = grows long × of arris of long × of arris of watch area =
× of A of × of S watch =a 6 watches =6a2
A V= A3 of × of V=a × A
3, rectangle
Side of A of area of C circumference S is long
Circumference =(is long wide) × 2
C=2(a B)
Area = long × is wide
S=ab
4, cuboid
Wide H of long B of A of area of V bulk S is tall
(Long × of =(of 1) watch area is wide × of long × Gao Kuan is tall) × 2
(Wide × of long × of 2) bulk = is tall
S=2(ab Ah Bh)
V=abh
5, triangle
H of bottom of S area A is tall
Tall ÷ of × of area = bottom 2
S=ah ÷ 2
By 2 ÷ of × of area of triangular tall =
2 ÷ of × of area of triangular bottom = are tall
6, parallelogram
H of bottom of S area A is tall
× of area = bottom is tall
S=ah
7, echelon
B of the bottom on S area A lays a foundationH is tall
On area =(next bottom) × tall ÷ 2
÷ of H of S=(a B) × 2
8, circle
Circumferential rate of π of circumference of S area CRadius of D diameter R
π of × of circumference = diameter
Radius of × of π of circumference =2 ×
π of × of radius of × of area = radius
C= π D
C=2 π R
S= π R2D=C ÷ πD=2r2 ÷ of ÷ of R=d ÷ 2 R=C π
π of S annulus = (R2-r2)
9, cylinder
Underside of tall S of V bulk H accumulates circumference of underside of C of R underside radius
× of circumference of underside of side area = is tall
