My KitchenCalc 8300 is a trusted piece of mind in the kitchen whenever I need to scale recipes or convert measurements on the fly. I also enjoy using it when converting from standard to metric measurements. I would like to see a parenthetical function to perform equations (such as determining BMI for patients, etc). Other than that, the KitchenCalc is an excellent product!

Very Useful 5 out of 5.0
User: , Executive Chef of The Westin Alexandria from Alexandria, VA

I find this calculator very useful and I have started giving them to my culinary associates. We use the calculators to calculate exactly how much soup/sauce or ingredients we will need for larger functions. Example, for 300 people I know we need 30 ml of sauce per person. For our production we need exact amounts. I also frequently use the timer. The size of the KitchenCalc is perfect for cooks’ pants; I usually keep one in my back pocket. We love the protective cover but sometimes find it a bit too thick…but at the same time without it we would break it or get it wet. The conversion words (the ones that are in blue above the number buttons on the pocket sized calculator) are a little small. Sometimes they are a bit hard to see in a commercial kitchen when you are trying to go fast. All in all, I love your product and have purchased 10 or 12 of these calculators; I give them to the cooks.

This calculator is the greatest tool for anyone who cooks. I am a single female who likes to cook one serving meals so I do not have leftovers and also so I do not make a lot of something in case I do not like it. Now I am able to try a wider variety of recipies. Thank you soo much!!!!!

I have been using this calculator for over 4 years now. I cannot do without it when planning a large meal. I am the "Chef" for my church, and I usually have to plan meals for many diverse functions. Thanks so very much for a wonderful kitchen tool.

This is a great product thatr fits into your top pocket and you can carry it around the kitchen. I have ahd several people ask me for the web site so they can buy one as well. If you are used to metric this calc is the best on the market for ease of use.

I've been using this calculator for 4 weeks and I wish I had 10 years ago. I take with me to the restaurant everyday. For the ease of converting/costing recipes alone it's worth every dollar.
