Convert fen(公分) to arm length

Learn how to convert 1 fen(公分) to arm length step by step.

Calculation Breakdown

Set up the equation

1.0 (f e n (公 分)) = x (a r m l e n g t h)

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

(m e t e r)

Left side: 1.0 (f e n (公 分)) = 10^{- 2} (m e t e r) = 10^{- 2} (m)

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

Insert known values into the conversion equation to determine

x

1.0 (f e n (公 分)) = x (a r m l e n g t h)

Insert known values =>

1.0 \times 10^{- 2} \times (m e t e r) = x \times 0.7 \times (m e t e r)

Or

1.0 \cdot 10^{- 2} \cdot (m) = x \cdot 0.7 \cdot (m)

Cancel SI units

1.0 \times 10^{- 2} \cdot (m) = x \times 0.7 \times (m)

Conversion Equation

10^{- 2} = x \times 0.7

Switch sides

x \times 0.7 = 10^{- 2}

Isolate

x

Multiply both sides by

(\frac{1.0}{0.7})

x \times 0.7 \times \frac{1.0}{0.7} = 10^{- 2} \times \frac{1.0}{0.7}

Cancel

x \times 0.7 \times \frac{1.0}{0.7} = 10^{- 2} \times \frac{1.0}{0.7}

Simplify

x = \frac{10^{- 2}}{0.7}

Solve

x

x \approx 0.0142857143 \approx 1.4286 \times 10^{- 2}

Conversion Equation

1.0 (f e n (公 分)) \approx 1.4286 \times 10^{- 2} (a r m l e n g t h)
