Convert cottah to qing(顷)

Learn how to convert 1 cottah to qing(顷) step by step.

Calculation Breakdown

Set up the equation

1.0 (c o t t a h) = x (q i n g (顷))

Define the base values of the selected units in relation to the SI unit

(s q u a r e m e t e r)

Left side: 1.0 (c o t t a h) = 67.0 (s q u a r e m e t e r) = 67.0 (m^{2})

Right side: 1.0 (q i n g (顷)) = \frac{2.0 \times 10^{5}}{3.0} (s q u a r e m e t e r) = \frac{2.0 \times 10^{5}}{3.0} (m^{2})

Insert known values into the conversion equation to determine

x

1.0 (c o t t a h) = x (q i n g (顷))

Insert known values =>

1.0 \times 67.0 \times (s q u a r e m e t e r) = x \times \frac{2.0 \times 10^{5}}{3.0} \times (s q u a r e m e t e r)

Or

1.0 \cdot 67.0 \cdot (m^{2}) = x \cdot \frac{2.0 \times 10^{5}}{3.0} \cdot (m^{2})

Cancel SI units

1.0 \times 67.0 \cdot (m^{2}) = x \times \frac{2.0 \times 10^{5}}{3.0} \times (m^{2})

Conversion Equation

67.0 = x \times \frac{2.0 \times 10^{5}}{3.0}

Switch sides

x \times \frac{2.0 \times 10^{5}}{3.0} = 67.0

Isolate

x

Multiply both sides by

(\frac{3.0}{2.0 \times 10^{5}})

x \times \frac{2.0 \times 10^{5}}{3.0} \times \frac{3.0}{2.0 \times 10^{5}} = 67.0 \times \frac{3.0}{2.0 \times 10^{5}}

Cancel

x \times \frac{2.0 \times 10^{5} \times 3.0}{3.0 \times 2.0 \times 10^{5}} = 67.0 \times \frac{3.0}{2.0 \times 10^{5}}

Simplify

x = \frac{67.0 \times 3.0}{2.0 \times 10^{5}}

Rewrite equation

\frac{1.0}{10^{5}} can be rewritten to 10^{- 5}

Rewrite

x = \frac{10^{- 5} \times 67.0 \times 3.0}{2.0}

Solve

x

x = 0.001005 = 1.005 \times 10^{- 3}

Conversion Equation

1.0 (c o t t a h) = 1.005 \times 10^{- 3} (q i n g (顷))
