of 2,685 topic-associated OpenAlex sources by lifetime output
FWCI compares papers with the same publication year, type, and field. 1.0 is the world average; above 1.0 is above expectation. This journal's median is 1.00, so its typical recent paper is in line with its field benchmark.
16% of recent papers rank in the global top 10% after field normalization. This is easier to compare across specialties than raw citation totals.
Volume is separated from citation accumulation so newer papers are not presented as weaker simply because they are newer.

ACS Omega's 2026 Journal Metrics Score is 4.5, from the August 2026 data release. The score is a two-year citation average computed from OpenAlex (CC0) data: citations received in the most recent complete year to works published in the two prior years, divided by the number of those works.
We have not found an official acceptance rate published by ACS Omega or its publisher, and Journal Metrics does not estimate one because submission counts are not public. What recent PubMed records do show is speed: accepted papers took a median of 106 days from submission to acceptance. To judge selectivity, compare ACS Omega's quartile and score with similar journals, or ask the editorial office.
ACS Omega's best quartile is Q1. By OpenAlex subfield: Q1 in Mechanics of Materials; Q2 in Renewable Energy, Sustainability and the Environment; Q2 in Molecular Biology; Q2 in Materials Chemistry. Quartiles rank journals by Journal Metrics Score within each subfield.
No. Journal Metrics computes the score independently from OpenAlex open data. Other providers use different citation databases, document types, and counting rules, so their published figures for ACS Omega will not match this score exactly. Compare journals using one source at a time.
ACS Omega accepts papers a median of 106 days after submission across 100 recent PubMed records with both dates; the middle half took 84–128 days. This includes peer review, editorial handling, and revisions.
PubMed records when a manuscript was received and accepted, not the individual review stages, so peer review time on its own is not available. The full time from submission to acceptance at ACS Omega, which includes peer review and revisions, has a median of 106 days. For the time to a first decision, check the journal's own website.
ACS Omega's median of 106 days from submission to acceptance is slower than 55% of comparable journals with PubMed timing data.
OpenAlex lists an indicative article processing charge of $1,685 USD for ACS Omega. This journal-level estimate may exclude taxes, waivers, discounts, or article-type fees, so confirm the current charge on the journal's website.
