Convert arm length to li(公里)

Learn how to convert 1 arm length to li(公里) step by step.

Calculation Breakdown

Set up the equation

1.0 (a r m l e n g t h) = x (l i (公 里))

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

(m e t e r)

Left side: 1.0 (a r m l e n g t h) = 0.7 (m e t e r) = 0.7 (m)

Right side: 1.0 (l i (公 里)) = 10^{3} (m e t e r) = 10^{3} (m)

Insert known values into the conversion equation to determine

x

1.0 (a r m l e n g t h) = x (l i (公 里))

Insert known values =>

1.0 \times 0.7 \times (m e t e r) = x \times 10^{3} \times (m e t e r)

Or

1.0 \cdot 0.7 \cdot (m) = x \cdot 10^{3} \cdot (m)

Cancel SI units

1.0 \times 0.7 \cdot (m) = x \times 10^{3} \times (m)

Conversion Equation

0.7 = x \times 10^{3}

Switch sides

x \times 10^{3} = 0.7

Isolate

x

Multiply both sides by

(\frac{1.0}{10^{3}})

x \times 10^{3} \times \frac{1.0}{10^{3}} = 0.7 \times \frac{1.0}{10^{3}}

Cancel

x \times 10^{3} \times \frac{1.0}{10^{3}} = 0.7 \times \frac{1.0}{10^{3}}

Simplify

x = \frac{0.7}{10^{3}}

Rewrite equation

\frac{1.0}{10^{3}} can be rewritten to 10^{- 3}

Rewrite

x = 10^{- 3} \times 0.7

Solve

x

x = 7 \times 10^{- 4}

Conversion Equation

1.0 (a r m l e n g t h) = 7 \times 10^{- 4} (l i (公 里))
