Convert arm length to em

Learn how to convert 1 arm length to em step by step.

Calculation Breakdown

Set up the equation

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

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 (e m) = \frac{1.0}{2835.0} (m e t e r) = \frac{1.0}{2835.0} (m)

Insert known values into the conversion equation to determine

x

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

Insert known values =>

1.0 \times 0.7 \times (m e t e r) = x \times \frac{1.0}{2835.0} \times (m e t e r)

Or

1.0 \cdot 0.7 \cdot (m) = x \cdot \frac{1.0}{2835.0} \cdot (m)

Cancel SI units

1.0 \times 0.7 \cdot (m) = x \times \frac{1.0}{2835.0} \times (m)

Conversion Equation

0.7 = x \times \frac{1.0}{2835.0}

Switch sides

x \times \frac{1.0}{2835.0} = 0.7

Isolate

x

Multiply both sides by

(\frac{2835.0}{1.0})

x \times \frac{1.0}{2835.0} \times \frac{2835.0}{1.0} = 0.7 \times \frac{2835.0}{1.0}

Cancel

x \times \frac{1.0 \times 2835.0}{2835.0 \times 1.0} = 0.7 \times \frac{2835.0}{1.0}

Simplify

x = 0.7 \times 2835.0

Solve

x

x = 1984.5 = 1.9845 \times 10^{3}

Conversion Equation

1.0 (a r m l e n g t h) = 1.9845 \times 10^{3} (e m)
