Use jq to display Limits/Allocation Ratio for a given Kubernetes namespace quota:

kubectl get quota -n my-namespace -o json | jq -r "$(curl -ks https://gist.githubusercontent.com/berttejeda/e89da293d9b3ed8183948caac2bdd09c/raw/9dc2617baaa7f389ad8cbd92d3a7049169ad0cbc/k8s.quotas.jq)"

Sample output:

    "quotaname": "default-12a3b",
    "limitsCpu": "360",
    "limitsCpu_used": "9",
    "limitsCpu_Allocation_Ratio": 2.5,
    "limitsMemory": "414Gi",
    "limitsMemory_used": "20Gi",
