## Overview

Two classic US-sports stats in one calculator. NFL passer rating uses the official four-component formula (each clamped to [0, 2.375], combined ((a+b+c+d)/6)×100) on a 0–158.3 scale — this is the public NFL passer rating, not ESPN's proprietary QBR. MLB mode computes ERA = 9×ER/IP and WHIP = (BB+H)/IP with correct baseball innings parsing (7.1 = 7⅓, 7.2 = 7⅔). Includes contextual tiers. For batting (AVG/OBP/SLG) use the Baseball Stats tool.

## Inputs

- **Stat mode** (select)
- **Pass attempts (ATT)** (number)
- **Completions (COMP)** (number)
- **Passing yards (YDS)** (number)
- **Touchdown passes (TD)** (number)
- **Interceptions (INT)** (number)
- **Innings pitched (IP)** (text): e.g. 7.2 (=7⅔)
- **Earned runs (ER)** (number)
- **Hits allowed (H)** (number)
- **Walks (BB)** (number)
- **Decimal places** (number)

## When to use

- Compare an NFL quarterback's passing performance using the public 0–158.3 passer-rating scale.
- Calculate a baseball pitcher's ERA and WHIP from a game, start, or season pitching line.
- Check component details and contextual performance tiers without calculating the formulas manually.

## How it works

- Choose NFL passer rating or MLB pitching (ERA + WHIP) from the Stat mode selector.
- In passer-rating mode, enter pass attempts, completions, passing yards, touchdown passes, and interceptions.
- In pitching mode, enter innings pitched, earned runs, hits allowed, and walks; use baseball notation such as 7.1 or 7.2 when needed.
- Set the number of decimal places from 0 to 3, then review the calculated result and available breakdown.

## Use cases

- Evaluate quarterback game lines by comparing efficiency, touchdowns, and interceptions in one rating.
- Review pitcher performance by calculating ERA and WHIP from earned runs, hits, walks, and innings.
- Create consistent sports-stat comparisons with selectable decimal precision and contextual tiers.

## Frequently asked questions

### What does the NFL passer rating calculator measure?

It calculates the official NFL passer rating on a 0–158.3 scale from completion rate, yards per attempt, touchdown rate, and interception rate.

### Is this the same as ESPN QBR?

No. It calculates the public NFL passer rating, not ESPN's proprietary QBR.

### How is MLB ERA calculated?

ERA is calculated as 9 × earned runs ÷ innings pitched.

### How is WHIP calculated?

WHIP is calculated as (walks + hits) ÷ innings pitched.

### What does 7.2 innings pitched mean?

In baseball notation, 7.2 means 7⅔ innings, not 7.2 standard decimal innings.
