Where can I find an online calculator that will enable me to compare the value of early 19th century British currency (pounds, shillings, pence) to modern-day US currency? Is there even such a thing?

We are shopping for a new home. We think we have found a home we want to put an offer on. The thing is, we have no clue how much the mortgage payments will be. We know the taxes and insurance, but there are so many online calculators giving us very different numbers for the monthly payment. [more inside]
One of my chemistry courses this semester requires that I use a non-programmable, scientific calculator on all exams. Do you know of any multi-line calculators with a similar keypad to my TI-84+ Silver edition? A lot of the calculators I've looked at on Amazon appear to be of the 2-line variety; the ones that have 4-lines don't have the ability to take inverse logs or to create custom-defined exponents. It'd be really nice to have as large a display as possible; money is no issue.
I'm taking Calc I this fall. I can borrow a graphing calculator for actual exams, but don't want to actually purchase one for day-to-day--or haul it around with me. I have an iPhone and a Nexus 7. Is there a graphing calculator app in one or the other app store that is clearly superior? I'm willing to pay, but under $10, ideally.

When should calculators be used in math class? What are good criteria for determining if a calculator should be used on a given set of problems?
I'm in my second year and so far my cheap little TI 30xIIs has worked fine for me, but my DC Circuits professor told the class that using the TI 30xIIs is cumbersome compared to the HP 35s for some material later in the semester. He said he highly recommends purchasing an HP 35s. I'm willing to spend the $50, but he's an Electrical Engineer teaching electrical classes. Would the HP 35s be good for me as a mechanical student?
Command-line calculator: I used to have a calculator program I put in c:\windows\system that took arguments, so I could type "c 5+2" into the start menu on W7 and a popup with the answer (7) would appear. Anyone know the name? Not quite a command-line calculator, since I want to pass in arguments and get a returned single value via popup.
Me: Poor student. Problem: The prices of TI calculators are 2 damn high. Looking for: Free software that performs wide range of operations (most important: a "matrix" function that is easy to punch in data).

A friend is working in an industrial plant and needs to frequently convert convert lbs to kgs. They currently use a calculator and divide by 2.2046, but find constantly punching in "xxxxx / 2.2046 =" tedious and error-prone. They'd like a reasonably-priced device (a calculator or PDA application) with reasonably sized buttons or a touch screen that would simplify this process. They'd like to have the answer displayed as digits were input (without needing to hit = or enter), as well as being able to clear the input amount without resetting the units to be converted.

Is there an online or otherwise calculator utility that can produce a multiplication column to the nearest integer if I need to (and I do need to) multiply a given integer (specifically, 8.57143) by all the integers from 1 to about 600, displayed in a list so that I don't have to multiply it each time? I may need to do other 600-deep columns with other decimally numbers, a few at most. I need to see the result, better yet print it. [more inside]
In 1997, I started making student loan payments, five months after graduating from graduate school. Shortly there after, in a sudden moment of sheer, blinding stupidity, I consolidated my loans, reducing my monthly payment and doubling the term of my loan. I do not want to make payments for 10 more years, however, I cannot figure out how to calculate the money I would save py doubling my payments this November. [more inside]

I'm working on something like a glorified graphing calculator application, based on a small functional programming language. Each input program describes a function of some number of parameters, and the app's job is to plot the function's output across various input ranges. Is there an existing language with an open-source parser I can reuse for this job instead of inventing and implementing a new language from scratch? [more inside]
