Pounds and Ounces Converter

Convert a combined pounds-and-ounces weight to total ounces, or back.


Pounds and Ounces Converter

Weights are often given in a combined “X lb Y oz” format — a baby’s birth weight, a package label — this converts that combined format to a single total.

How it works

Multiplying the pounds by 16 and adding the ounces gives total ounces; the reverse splits a total ounces figure into whole pounds and a remaining ounces value.

What this does not include

This does not include a plain single-value ounces-to-pounds conversion — for that simpler case, use this site’s ounces-to-pounds converter instead.

How to use this calculator

  1. Enter either the pounds and ounces separately, or a total ounces value.

Frequently asked questions

Why is this different from a plain ounces-to-pounds converter?

Because real-world weights are often already split into a combined “X lb Y oz” format rather than a single number — this handles that combined format directly, the same way a height calculator handles feet and inches together.

What’s a common use for this?

Converting a baby’s birth weight (commonly given as pounds and ounces) into a single total-ounces figure for tracking or comparison.

Can the ounces value exceed 16?

No — this calculator treats ounces as the remainder after whole pounds are removed, so it stays below 16; a total that would exceed that rolls into an additional whole pound instead.

L. Berg writes the measurement and unit-conversion calculators, from everyday length and weight conversions to the less obvious ones where definitions differ between systems. The work centres on getting conversion factors exactly right and flagging the places where a "standard" unit quietly means two different things. Precision here is mostly a matter of refusing to round early.

Particular attention goes to units whose definitions differ between measurement systems, where a plausible-looking factor can be quietly wrong.
