## How to Use the 1/4 Mile ET Calculator

Welcome to the 1/4 Mile ET Calculator! This tool helps you estimate your car's performance on a drag strip based on two key factors: the weight of your car and its wheel horsepower (HP). Here’s how it works:

**Input Your Car's Weight**: Enter the weight of your car in pounds. The weight affects how quickly your car can accelerate, so it's an important factor in calculating performance.**Enter Your Car's Wheel Horsepower**: Input the wheel horsepower (HP) of your car. Wheel horsepower is the power measured at the wheels of the car and is a more accurate reflection of your car's actual performance on the track.**Calculate Your Performance**: Click the "Calculate ET" button. The calculator will use the information provided to estimate the following:**60 Foot Elapsed Time**: This is the time it takes for your car to cover the first 60 feet of the drag strip.**1/8 Mile Elapsed Time**: This is the time it takes to cover the first 1/8 mile of the track.**1/4 Mile Elapsed Time**: This is the total time it takes to complete a full 1/4 mile drag strip run.**1/4 Mile Trap Speed**: This is the speed of your car as it crosses the finish line at the end of the 1/4 mile.

## Understanding the Results

**60 Foot Elapsed Time**: A quicker 60-foot time indicates better initial acceleration.**1/8 and 1/4 Mile Elapsed Times**: Shorter times mean faster overall performance.**1/4 Mile Trap Speed**: A higher trap speed shows how fast your car is going at the end of the 1/4 mile, reflecting its top-end power.

The calculator uses reference values and adjusts based on your car's weight and horsepower to give you realistic performance estimates. Keep in mind that these are estimates and actual track conditions can affect the results.

Feel free to experiment with different weight and horsepower values to see how changes might impact your car’s performance on the drag strip. Happy racing!
