Resolution scale calculator Calculate resolution downscaling options for video editing. Fill in the resolution you have and it will show all the scales that won't result in half pixels in a list. Click on a result to see an example ratio and click on the example to see it in full-scale.

Use our Differential Gear Ratio Calculator page to determine the best ring and pinion gear ratio for your vehicle. Installation of the correct ring and pinion gear ratio will help optimize performance, fuel economy and overall driveability.

## Tire Diameter Calculator

In order to select the ideal differential gear ratio, the first thing you will need to know is your actual tire diameter. The simplest method is to measure the height of the tire from the ground to the top of the tire.

If you don’t actually have the tires installed on the vehicle yet, use the metric tire diameter calculator below to determine tire diameter (height) using metric size designations.

• Using the Ratio Calculator. Resort to the help of this amazing ratio calculator when you have you settle ratio/proportion problems and check equivalent fractions. Despite the fact that you cannot enter a ratio of 4/5 into this calculator, it accepts values such as 4:5, for example, 4/3 should be written as 4:3.
• Enter a desired width for a 16:9 HD size video to get the width and height needed to maintain the aspect ratio when resizing your original video. WIDTH: HEIGHT: playing with old school Standard Definition? Use the 4:3 Aspect Ratio Calculator instead. This one works great for images too. Unfortunately, bills need to be paid.
• The Horowitz index for Lung Function (P/F ratio) assesses lung function, particularly in intubated patients. This is an unprecedented time. It is the dedication of healthcare workers that will lead us through this crisis.
• HD.Calc was created as an extension of SEER.Stat that allows the user to import SEER data or other population-based health data, such as National Health Survey sample data from the National Health Interview Survey (NHIS) or the Behavioral Risk Factor Surveillance System (BRFSS), and calculate any of eleven disparity measures.

Metric tire specifications use a three number format, such as 275/75R16, where 275 is the WIDTH of the tire tread in millimeters, 75 is the ASPECT (or percentage of tread width to yield the sidewall height), and 16 is the WHEEL diameter. Using the calculator below and the numbers in this example, the calculated value will be 32.24″.

The calculated value should be used only as a guideline for RPM calculations. Tires with identical specifications that are made by different manufacturers may have different actual diameters.

Truck and off road tires may have a specification like 30×9.5R15, where 30 is the tire diameter, 9.50 is the tread width and 15 is the wheel diameter. You don’t need the tire diameter calculator in this case, but be advised that most stated tire sizes rarely match the actual tire height. In the example above, 30 might not be completely accurate.

## RPM Calculator

Use the RPM calculator to determine what RPM your engine will run based on gear ratio, tire diameter, transmission and MPH. You can try various combinations to come up with an appropriate combination of ring and pinion gear ratio and tire diameter for your vehicle. The RPM calculator should be used as a guideline for comparative purposes only. Your vehicle will probably run at different RPM’s than those you calculate.

The Health Disparities Calculator (HD*Calc) is statistical software designed to generate multiple summary measures to evaluate and monitor health disparities (HD). HD*Calc was created as an extension of SEER*Stat that allows the user to import SEER data or other population-based health data, such as National Health Survey sample data from the National Health Interview Survey (NHIS) or the Behavioral Risk Factor Surveillance System (BRFSS), and calculate any of eleven disparity measures.

HD*Calc supports the use of a range of health disparities measures, allowing researchers to select and apply different measures to their data. HD*Calc was originally developed to expand the range of measures for evaluating health disparities related to cancer. However, since it can be used with any dataset, HD*Calc can be used in any research arena. Cross-sectional and trend data (e.g., cancer rates, survival, stage at diagnosis) categorized by disparity groups (e.g., area-socioeconomic status, race/ethnicity, geographic areas) can be imported into HD*Calc to generate four absolute, seven relative summary measures of disparity, and two pair comparison measures. The results are displayed as tables and charts, which may be exported for use in other applications. Read more about Health Disparity Measures in HD*Calc.

The readme.txt(TXT, 5 KB) distributed with the software includes a description of the revisions made for this release.

## Installation

Some users receive a Windows warning that they do not have authorization to run the installation program. If that happens, save the installation file to your computer. Right-click the file and select 'Run as administrator'to begin the installation process.

## Training and Help

In addition to the HD*Calc Webinars, a range of tutorials and technical support resources are available and will introduce you to the rationale behind the tool and help you get started.

We would appreciate any feedback to help us improve the software for future releases. Please send any comments or questions requiring technical support to [email protected]

## Publications

Several publications discuss HD*Calc or analyze data using the HD*Calc software.
