Kg to Fl Oz Formula

The formulas below convert kilograms to fluid ounces and back via density ฯ (g/mL): first find volume in mL as mL = (kg ร— 1000) รท ฯ, then divide by 29.5735295625 for US fl oz or 28.4130625 for Imperial fl oz.

\mathrm{fl\,oz}_{\mathrm{US}} = \frac{1000\,m_{\mathrm{kg}}}{\rho\,(\mathrm{g/mL})\cdot 29.5735295625}
  • 1 kg = 1000 g
  • 1 US fl oz = 29.5735295625 mL
  • 1 Imperial fl oz = 28.4130625 mL
  • mL = g รท ฯ and g = mL ร— ฯ (ฯ in g/mL)

* Assumes water (ฯ = 1.000 g/mL) at ~20ยฐC. 1 US fl oz = 29.5735295625 mL.

How do you convert kilograms to fluid ounces? Convert kg to grams (ร—1000), divide by density ฯ (g/mL) to get mL, then divide by 29.5735295625 for US fl oz or 28.4130625 for Imperial fl oz.

How do you convert fluid ounces to kilograms? Multiply fl oz by mL per fl oz (US or Imperial) to get mL, multiply by ฯ to get grams, then divide by 1000 to get kilograms.

Example Problem

Convert 2.5 kg of honey to US fluid ounces (ฯ โ‰ˆ 1.420 g/mL).

Use fl ozUS = (kg ร— 1000 รท ฯ) รท 29.5735295625.

fl oz = (2.5 ร— 1000 รท 1.420) รท 29.5735 โ‰ˆ 59.532 US fl oz.
