A ratio calculator is a tool that can help you find the ratio of two or more numbers, fractions, or quantities. A ratio is a way of comparing or expressing the relationship between two or more values. For example, if there are 4 boys and 6 girls in a class, the ratio of boys to girls is 4:6 or 2:3. A ratio calculator can simplify, compare, or solve for an unknown value in a ratio. You can use a ratio calculator for various purposes, such as cooking, scaling, mixing, or dividing.

A common ratio calculator is a tool that can help you find the common ratio of a geometric sequence. A geometric sequence is a sequence of numbers where each term is obtained by multiplying the previous term by a constant value, called the common ratio. For example, the sequence 2, 6, 18, 54, ... is a geometric sequence with a common ratio of 3. A common ratio calculator can find the common ratio of a given geometric sequence, or generate a geometric sequence from a given common ratio.

A debt to income ratio calculator is a tool that can help you measure your financial health by comparing your monthly debt payments to your monthly income. A debt to income ratio (DTI) is a percentage that shows how much of your income goes towards paying your debts, such as loans, credit cards, mortgages, etc. A lower DTI means that you have more money left over after paying your debts, which can improve your chances of getting approved for loans or credit cards. A higher DTI means that you have less money left over after paying your debts, which can indicate financial stress or risk of defaulting on your payments. A debt to income ratio calculator can help you calculate your DTI by adding up your monthly debt payments and dividing them by your monthly income.

A gear ratio calculator is a tool that can help you determine the speed, torque, or power of a rotating system that consists of two or more gears. A gear ratio is a ratio that shows how many times a driver gear (the gear that provides the input force) rotates compared to a driven gear (the gear that receives the output force). For example, if a driver gear with 10 teeth rotates one time, and it is connected to a driven gear with 20 teeth, the gear ratio is 10:20 or 1:2. A gear ratio calculator can help you find the gear ratio of a given system

A power to weight ratio calculator is a tool that can help you measure the performance of a vehicle, engine, or athlete by comparing the power output to the weight. A power to weight ratio (PWR) is a ratio that shows how much power (in watts) is generated per unit of weight (in kilograms). A higher PWR means that more power is produced for a given weight, which can indicate better acceleration, speed, or efficiency. A lower PWR means that less power is produced for a given weight, which can indicate slower acceleration, speed, or efficiency.

A cholesterol ratio calculator is a tool that can help you assess your risk of developing heart disease by comparing the levels of good and bad cholesterol in your blood. Cholesterol is a type of fat that is essential for the normal functioning of the body, but too much of it can clog the arteries and cause heart problems. There are two main types of cholesterol: high-density lipoprotein (HDL), which is the good cholesterol that helps remove excess cholesterol from the blood, and low-density lipoprotein (LDL), which is the bad cholesterol that builds up in the arteries and increases the risk of heart disease. A cholesterol ratio is a ratio that shows the proportion of HDL to LDL in your blood. A lower cholesterol ratio means that you have more HDL and less LDL, which can protect your heart.

A golden ratio calculator is a tool that can help you find the golden ratio of a given length, width, height, or angle. The golden ratio is a special number that is approximately equal to 1.618. It is also known as the divine proportion, the golden mean, or the golden section.
