Convert pennyweight to firkin

Learn how to convert 1 pennyweight to firkin step by step.

Calculation Breakdown

Set up the equation

1.0 (p e n n y w e i g h t) = x (f i r k i n)

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

(k i l o g r a m)

Left side: 1.0 (p e n n y w e i g h t) = 1.55517384 \times 10^{- 3} (k i l o g r a m) = 1.55517384 \times 10^{- 3} (k g)

Right side: 1.0 (f i r k i n) = 25.40117272 (k i l o g r a m) = 25.40117272 (k g)

Insert known values into the conversion equation to determine

x

1.0 (p e n n y w e i g h t) = x (f i r k i n)

Insert known values =>

1.0 \times 1.55517384 \times 10^{- 3} \times (k i l o g r a m) = x \times 25.40117272 \times (k i l o g r a m)

Or

1.0 \cdot 1.55517384 \times 10^{- 3} \cdot (k g) = x \cdot 25.40117272 \cdot (k g)

Cancel SI units

1.0 \times 1.55517384 \times 10^{- 3} \cdot (k g) = x \times 25.40117272 \times (k g)

Conversion Equation

1.55517384 \times 10^{- 3} = x \times 25.40117272

Switch sides

x \times 25.40117272 = 1.55517384 \times 10^{- 3}

Isolate

x

Multiply both sides by

(\frac{1.0}{25.40117272})

x \times 25.40117272 \times \frac{1.0}{25.40117272} = 1.55517384 \times 10^{- 3} \times \frac{1.0}{25.40117272}

Cancel

x \times 25.40117272 \times \frac{1.0}{25.40117272} = 1.55517384 \times 10^{- 3} \times \frac{1.0}{25.40117272}

Simplify

x = \frac{1.55517384 \times 10^{- 3}}{25.40117272}

Solve

x

x \approx 0.0000612245 \approx 6.1224 \times 10^{- 5}

Conversion Equation

1.0 (p e n n y w e i g h t) \approx 6.1224 \times 10^{- 5} (f i r k i n)
