Weights and Measures

Applying Collective Standards of Equity and Fairness to Consumers and Businesses

Picture of gas pump nozzleThe Department of Weights and Measures assures equity in trade by administering and enforcing the New York State Agriculture and Market Laws which deal with the accuracy and proper usage of all commercial weighing and measuring devices.

The Department is responsible for the inspection of commodities as well as the testing and inspection of weighing and measuring devices in supermarkets, industrial establishments, gas stations, hardware stores, pharmacies, concrete and asphalt plants, taxi meters, salvage yards, fabric stores, jewelry stores, farm markets, petroleum bulk plants and fuel oil trucks.

***ALL commerical use devices MUST be LEGAL for trade!  Please click on listing of approved devices to determine if it is legal for trade and/or  New York State Weights and Measures laws, rules and regulations related to  Weighing and Measuring devices.

Unit pricing is required by law and random inspections for pricing accuracy are conducted.

The monitoring of commercial business enterprise standards requires frequent inspection and testing of all weighing and measuring devices within the County.  All standards used in county testing follow national standards (NIST).  Inaccurate measuring devices and meters are reported and ordered for repair by the inspectors. Civil penalties are imposed for non-fraudulent violations while fraudulent cases are referred to the County Attorney for prosecution.

If you have a commercial-use measuring device (e.g. scale, gasoline pump, taximeter, fuel truck meter) that is used to determine the price of a commodity or service rate, you are REQUIRED to contact this department at 585-753-7933 for testing and certification.

The Department also participates in the New York State Petroleum Quality Program which assures the quality of gasoline and other motor fuels by sampling at retail stations.

Pay Only for the Product . . . Not the Packaging

When you buy jelly in a glass jar, you should pay only for the weight of the jelly. If you buy potato salad at the deli counter, you should pay only for the salad, not for the weight of the container.

The weight of the packaging materials is referred to as tare for more information

Getting What You Pay For

It's hard to be a smart consumer today. You think about the products you buy and the amount you can spend. Can I afford this? Is it the best buy? Am I getting my money's worth?.... Click for more information

Buying Heating Fuel

Home heating fuel and propane are sold by volume or weight. When these products are delivered to your home, the seller must give you a “delivery ticket” showing the name and address of the buyer and seller, the delivery date, the amount and type of fuel delivered. The unit price of the fuel should also be on the delivery ticket unless you have a special arrangement with the seller.  The amount of product delivered must be 'metered' onto the ticket—it cannot be written in by hand.

If you have a problem with the delivery of home heating fuel or propane, contact this office at 585 753-7933.

Buying Firewood

Some people heat their homes with firewood, which is sold by a measurement called a “cord.”   Click for more information.

If you have a problem with the delivery of firewood and you cannot resolve it, contact this office at 585 753-7933.

Buying Gasoline

Good measurement is important when you buy gasoline and motor fuel. These fuels are sold by volume in gallons or liters. The price you pay for gasoline will depend upon:

  1. The octane level, which may affect the performance of your car;
  2. The amount you buy; and
  3. Any discounts offered.

A computer in the gasoline pump calculates what you owe based on the amount and the unit price of the gasoline. When comparing prices, be sure to compare gasoline with the same octane rating. Usually, the higher the octane rating, the higher the price. Also check to be sure you are comparing the same unit of measurement. Is the price per gallon or per liter?

Weights and measures officials routinely check gasoline pumps for accuracy. Pumps found to be out of tolerance are sealed from use and ordered repaired and must be re-tested before they can be put back in use. New pump installations must be inspected and tested prior to being put into service. In many areas, they also check gasoline storage tanks to be sure that stations are selling the octane level advertised. If violations are found, the seller can be fined and the product can be removed.

Gasoline stations offering their mid-grade or high-grade product at the low-grade price on a certain day of the week must change the unit price of the product in the computer in the gasoline pump and calcuate accordingly.

What You Can Do

   Be sure the attendant or you are using the correct pump.

  • The octane rating and the price per gallon or liter must be clearly marked on each pump.
  •  Be sure the pump is set to zero before any gasoline is pumped.
  •  Check the price by multiplying the number of gallons or liters by the unit price. Be sure this shows as the total due.
  •  Figure the cash discount, if any. Check that you are charged the right amount.
  •  Check your receipt to be sure the amount billed is the amount on the pump.


If you have a problem or question that you cannot resolve with the gas station, contact the Department of Weights Measures at 585 753-7933.

Weights and Measures Consumer Tips At the Gas Pump

Do not overfill your gas tank.

When the nozzle shuts off on its own, Stop! Gas tanks are designed to allow room for the vapors produced by the product. Routinely over-filling can eventually cause your tank to leak. Your 2 gal, 5 gal, etc. gas can will always hold more than its stated capacity. It is also designed to allow for the product’s vapors.

Plastic cans which are consistently filled to the top, will eventually stretch due to the product expansion. Metal cans will eventually leak, for the same reason.

If the unit price of gasoline is $3.799 and you by exactly one (1) gallon, you will be charged $3.80 as there is no way to pay 9/1000 of a cent.

Be sure the product has stopped flowing before removing the nozzle

Do Not smoke and pump!

Do Not use Cell phones!

Be aware of static


Skimming devices have been found on some ATMs, gas pumps and other machines where a credit/debit card can be used. 

These devices read credit/debit card information.  Some skimming dvices can be used solely by walking by you and scanning your purse/pocket for credit/debit card information. 

Here are some tipes to keep your credit/debit/personal information safe:

  • Use caution when using your credit/debit card
  • Keep your credi/tdebit card in a RFID protecive sleeve when not is use
  • Pay inside.  Pay with a credit card or use your debit card as a credit card
  • Protect your PIN from view and against hidden cameras
  • Keep your card in sight when paying.  Be aware that workers can use hand-held skimmers to skim your information before swiping it for payment services. 

When pumpimp gas, use pumps closets to the building to lessen chances of pumps being accessed illegally.

Some gas stations are using tamper resistant security tape to help protect the pumps from skimming devices.  Look for this tape by the credit card slot or the upper part of the pump.  If the seal is cut, broken or the word "VOID" is displayed, it is an indication that someone has entered the inside of the pump to possibly install a skimming device.  DO NOT USE THIS PUMP.  Alert the station's management.

There are also skimming dvices that fit over credit card readers.  Grab hold of the credit card slot and pull.  If the unit comes loose or separates fromt eh pump or ATM, DO NOT USE this machine.  Contact the business manager and police. 

Monitor your bank statements for suspect transactions.

Be aware of your surroundings at all times.

Call 911 to report suspicious activity at gas pumps.
