Pulley Calculator - Centers - RPM - Belt Length and Speed
Enter any 3 known values to calculate the 4th
If you know any 3 values (Pulley sizes or RPM) and need to calculate the 4th, enter the 3 known values and hit Calculate to find the missing value.
For example, if your small pulley is 80mm diameter, and spins at 1000 RPM, and you need to find the second pulley size to spin it at 400 RPM, Enter Pulley1 80, Pulley 1 RPM 1000, Pulley 2 RPM 400, and hit Calculate to find the second pulley diameter.
If you're cutting blocks, concrete, stone or ANYTHING and there's DUST - DON'T TAKE THE RISK
Don't cut it, or cut it wet so there's NO DUST - Silicosis Sucks
And if you're cutting wet, wear a mask - theres dust in the spray mist too!

Aspect Ratio Calculator. Use the form below to calculate the missing value for a particular aspect ratio. This is useful, for example, when resizing photos or video. Common ratios: Round results to the nearest whole number. Picture Frame Calculator. Select Moulding Width Or A Roma Moulding Product. Moulding width:. Product number: 2. Select Frame Size Inside. Outside widthLabel.
- Perhaps more important than the photograph to frame ratio is the frame to mat ratio. Whenever possible, avoid pairing a mat with a frame the same size or larger. As a general rule, your mat should always be 1.5 times as wide as your frame, or wider. If the mat is smaller than the frame, you run the risk of the artwork appearing stuffed into the.
- This is a simple calculator to help you work out the aspect ratio of an image, and the size of that image when it's resized, keeping the same proportions.
- Sometimes video players or image frames could add up to 20 – 30 pixels and as a result aspect ratio will not be as it truly is. You may also find useful other aspect ratio calculators: Standard Definition (SD / 4:3).

For example, if your small pulley is 80mm diameter, and spins at 1000 RPM, and you need to find the second pulley size to spin it at 400 RPM, Enter Pulley1 80, Pulley 1 RPM 1000, Pulley 2 RPM 400, and hit Calculate to find the second pulley diameter.
Multiple Pulleys - RPM Reduction To calculate multiple pulley sets, where the first driven (large) pulley shaft drives the second driver (small) pulley, and so on, enter first (small) driver pulley RPM and pulley set diameters and centers separated by commas and - as shown below. The RPM of the first driven (large) pulley is transferred to second set small (driver) pulley and so on. The sets of pulleys will be drawn at the bottom of the page with each set RPM reductions and total RPM reduction through all entered sets. In this instance, the initial small driver pulley RPM is 2000. The small pulley diameter is 6', large pulley diameter is 12' and centers is 16'. The second set small pulley diameter is 7', large pulley diameter is 12' and centers is 18'.

Ratio Calculator In Simplest Form
Copyright © 2021 - blocklayer.comMymm f/lens, on asensor, is equivalent to a157.5mmf/2.1lens. The crop factor for that sensor is 1.5x.
? Useful Info About Crop Factors:
- ◉ A crop factor is the multiplier that needs to be used to compare the full-frame equivalent focal length and maximum aperture of a lens when used on a different-sized sensor. That means that sensors that are smaller than a full-frame (35mm) sensor will crop out a part of the image that's received by the lens, effectively cropping the image. Calculating the effective focal length using the crop factor therefore allows you to determine the effective field of view for that lens when used on a camera with a smaller sensor.
- ◉ In that sense, full-frame sensors are the lingua franca of sensors, meaning that they are the sensor size used as the reference point.
- ◉ Popular smaller sensor sizes are Micro Four Thirds, APS-C and APS-H. In this tool I decided to only include the most popular sensor sizes, but you can get in touch with me here if you'd like me to include more sensor sizes.
- ◉ Larger sensors than full-frame, like medium format sensors, have a reverse crop factor. Cropped medium format sensors include sensors for Pentax and Fujifilm medium format cameras as well as the Hasselblad X1D.
- ◉ The crop factor is also used on the aperture to give us the maximum effective aperture equivalent on a full-frame camera. That means that we can have a better idea of the amount of background blur and depth of field that a lens will be able to produce.
