Convert pound to kilogram

Learn how to convert 1 pound to kilogram step by step.

Calculation Breakdown

Set up the equation

1.0 (p o u n d) = x (k i l o g r a m)

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 o u n d) = 0.5 (k i l o g r a m) = 0.5 (k g)

Right side: 1.0 (g r a m) = 10^{- 3} (k i l o g r a m) = 10^{- 3} (k g)

Define the values of the selected prefixes

Right side: k i l o = k = 10^{3}

Insert known values into the conversion equation to determine

x

1.0 (p o u n d) = x (k i l o g r a m)

Insert known values =>

1.0 \times 0.5 \times (k i l o g r a m) = x \times 10^{3} \times 10^{- 3} \times (k i l o g r a m)

Or

1.0 \cdot 0.5 \cdot (k g) = x \cdot 10^{3} \times 10^{- 3} \cdot (k g)

Cancel SI units

1.0 \times 0.5 \cdot (k g) = x \times 10^{3} \times 10^{- 3} \times (k g)

Conversion Equation

0.5 = x \times 10^{3} \times 10^{- 3}

Simplify

0.5 = x

Switch sides

x = 0.5

Solve

x

x = 5 \times 10^{- 1}

Conversion Equation

1.0 (p o u n d) = 5 \times 10^{- 1} (k i l o g r a m)
